ALIGNMENT PROCEDURE
13.2g 4S123
1937 Mastorplece Model 733 WARNING: The following information is to be used only by an experienced serviceman with the proper equipment. In
most cases it is necessary only when set has been tampered with or damaged by accident. I.F. ALIGNMENT: Connect signal generator, through .00025 cond., to grid cap of /C6 tube. Set signal generator at 456
K.C. (this must be accurate), dial pointer at 1700 K.C. Short out oscillator section (center section) of variable cond. gang. Connect suitable output meter across voice coil of loud speaker. (If output meter is not available it will be necessary to adjust by ear, using the loudest note from signal generator.) Increase attenuator until output meter shows deflection or a note is heard from signal generator. Carefully adjust I.F. transformer trimmers for greatest deflection of meter or loudest note from generator. Reduce generator output as intensity of signal increases as I.F.s are tuned nearer their original 456 K.C. setting. Signal should be just audible by ear. Go back over the adjustments to be sure they are correct. Remove short from oscillator section of variable cond. and adjustment is complete.
B.C.-R.F. ALIGNMENT: (1) Connect signal generator, through .00025 cond., to antenna post Al. Short wave switch in broadcast position. (2) Set signal generator and dial pointer to /4007[-C. (3) Adjust ose. B.C. trimmer "A" (see diagram) for greatest deflection of meter or loudest note. (4) Set generator and dial pointer to 1400 K.C. Adjust antenna B.C. trimmer and trimmer "E" for greatest deflection of meter or loudest note. (5) Set generator and dial pointer to 600 K.C. Adjust trimmer "D" for greatest deflection or loudest note. (This adjustment is critical and must be accurate.) Rock cond. gang across 600 K.C. note while adjusting trimmer "D." Repeat adjustment at least twice to be sure it is correct.
POLICE AND AMATEUR BAND ADJUSTMENT: (1) Set switch in Police -Amateur position. Connect signal gen. to ant. post Al through 400 ohm resistor. (2) Set gen. and dial pointer to 6 meg. (6000 K.C.). Carefully adjust trimmer "B" for greatest deflection or loudest note. Check adjustment with gen. and dial pointer at 2 meg. (2000 K.C.).
FOREIGN BAND ADJUSTMENT: (1) Set switch in Foreign position. Connect gen. to ant. post Al through 400 ohm resistor. (2) Set generator and dial pointer to 18 meg. (18000 K.C.). This must be accurate. (3) Carefully adjust trimmer "C" and ant. S.W. trimmer for greatest deflection or loudest note. Check adjustment with gen. and dial pointer at 7 meg. (7000 K.C.). This completes all R.F. adjustments.

WARNING: The following information is to be used only by an experienced serviceman with the proper equipment. In most cases it is necessary only when set has been tampered with or damaged by accident.
I.F. ALIGNMENT: Connect signal generator, through .00025 cond., to grid cap of 6D8 tube. Set signal generator at 456 K.C. (this must be accurate), dial pointer at 1790 K.C. Short out oscillator section (center section) of variable cond. gang. Connect suitable output meter across voice coil of loud speaker. (If output meter is not available it will be necessary to adjust by ear, using the loudest note from signal generator.) Increase attenuator until output meter shows deflection or a note is heard from signal generator. Carefully adjust I.F. transformer trimmers for greatest deflection of meter or loudest note from generator. Reduce generator output as intensity of signal increases as I.F.s are tuned nearer their original 456 K.C. setting. Signal should be just audible by ear. Go back over the adjustments to be sure they are correct. Remove short from oscillator section of variable cond. and adjustment is complete.
B.C.-R.F. ALIGNMENT: (1) Connect signal generator, through .00025 cond., to antenna post Al. Short wave switch in broadcast position. (2) Set signal generator and dial pointer to 1700 K.C. (3) Adjust ose. B.C. trimmer "A" (see diagram) for greatest deflection of meter or loudest note. (4) Set generator and dial pointer to 1400 K.C. Adjust antenna B.C. trimmer and trimmer "E" for greatest deflection of meter or loudest note. (5) Set generator and dial pointer to 600 K.C. Adjust trimmer "D" for greatest deflection or loudest note. (This adjustment is critical and must be accurate.) Rock cond. gang across 600 K.C. note while adjusting trimmer "D." Repeat adjustment at least twice to be sure it is correct.

FIG. I.-PUSH BUTTON COMPENSATOR LOCATIONS
LIGHT -BEAM REPRODUCER ADJUSTMENTS To reproduce the sound from o record, the light beam Of the reproducer must be carefully positioned -on the light sensitive cell. If the light beam is not core - fully set, the sound reproduction will be distorted, weak or, if the light beam is completely on or off the cell, the phonograph will be silent.
If any of these conditions exist, the following adjustment procedure should be made:
NOTE-These adjustments should be made with the power line voltage at 117 volts A.C.
A. ADJUSTING WIDTH OF LIGHT BEAM To moke this adjustment push the lamp socket assembly into its holder until a clear image of the lamp filament appears on the light cell. The socket should then be slightly pushed in beyond this point until the rectangular spot of light is S/32" in width. The socket assembly is now rotated no that the spotlight is vertical.
B. POSITIONING THE LIGHT REAM To position the light beam on the light cell, turn the adjusting screw at the lower left side of the reproducer until the spot is half on the cell and half on the metal frame surrounding the cell.
C. ADJUSTING INTENSITY OF LAMP When shipped from the factory, the lamp of the reproducer is adjusted for best operating efficiency. The intensity of the light from the lamp is adjusted by Compensator No. 17 located on the radio chassis. Under ordinary circum- stances, an adjustment will not be necessary. When replacing the reproducer or lamp, however, it may be necessary to readjust the light intensity. In this case the compensator is adjusted as follows:
I. Turn volume control on full and play a record.
2. While the record is playing, turn compensator 17 in the direction neces- sary to obtain the best operating point without distortion. By turning the compensator the strength of the pick-up output is increased or decreased.
D. INSTALLING NEW LAMP When installing a new lamp in the socket, there are two positions in which the lamp can be inserted. Ordinarily, either of these positions can be used. In
some cases, however, due to the lamp filament being off center, the lamp must
be inserted in the position that gives the best centering of the spot of light on the vibrating mirror.

ALIGNING R. F. AND I. F. COMPENSATORS The following procedure is the same for both models:
EQUIPMENT REQUIRED
I. SIGNAL GENERATOR: Covering the frequency range of the re-
ceiver, such as Philco Model 070.
2. ALIGNING INDICATOR: Either a vacuum tube voltmeter or an
MODELS 42-1010, 42-1011E
audio output meter may be used os an aligning indicator. Philco
Models 027 and 028 circuit testers contain both these meters.
3. TOOLS: Philco Fiber Screw Driver, Part No. 45.2610.
CONNECTING ALIGNING INSTRUMENTS
Either o vacuum tube voltmeter or an audio output meter may be
used as a signal indicator when adjusting the receiver.
Vacuum Tube Voltmeter: To use the vacuum tube voltmeter as an
aligning indicator, make the following connections: Attach the nega-
tive (-) terminal of the voltmeter to any point in the circuit where
the A. V. C. voltage can be obtained. Connect the positive (+ terminal of the vacuum tube voltmeter to the chassis.
Audio Output Meter: Terminal No. I is provided on the loop aerial
panel for connecting one lead of the audio output meter to 'he voice
coil of the speaker. The other lead of the meter is connected to the
chassis. When using these connections, the lowest A. C. scale of the
meter must be used. (0 to 10 volts).
The audio output meter can also be connected between the plate of
the output tube and the ground of the chassis.
Signal Generator: The radio can be aligned in the cabinet or removed
from the cabinet. When adjusting the "I. F." padders, the high side
of the signal generator is connected through a .1 mfd. condenser so
the lug on the aerial section of the tuning condenser. The ground or
low side of the signal generator is connected to the ground of the
receiver.
When aligning the R. F. padders with the radio in the cabinet, a
loop is made from a few turns of wire and connected to the signal
generator output terminals: the loop is then placed two or three feet
from the loop in the cabinet. If the radio is aligned outside of the
cabinet without the loop connected an aerial input transformer, Part
No. 76-1134, will be required. Insert the transformer into the external
aerial socket on the rear of the chassis. Connect the high output terminal of the signal generator to the terminal on the transformer.
Connect the ground terminal to the chassis.
After connecting the aligning indicator, adjust the compensators in
the order shown in the tabulation below. Locations of the compen-
sators are shown below. If the output meter pointer goes off scale
when adjusting the compensators, reduce the strength of the signal
from the generator.

NOTE A-DIAL CALIBRATION: In order to adjust the receiver cor ectly, the maximum output on the first signal peak from the tight position (screw alt
dial must be oligned to track properly with the tuning condenser. To adjust the dial, proceed os follows: With the tuning condenser closed (maximum capacity), set the dial pointer on the extreme left index line of the low fre- quency end of the broadcast stole. The arrangement of the drive cable in this position is shown in the schematic.
NOTE B-When adjusting the low frequency compensator of Range One (Broadcast) or the aerial padders of the high frequency tuning range: the receiver Tuning Condenser must be adjusted (rolled) os follows: First, tune the compensator for maximum output, then vary the tuning condenser of the rece -ver for maximum output. Now turn the compensator slightly to the right or left and again vary the receiver tuning condenser for maximum output. This procedure of first setting the compensator and then varying the -tuning condenser is continued until maximum output rending is obtained.
NOTE C-To accurately adjust the high frequency oscillator compensator fo the fundamental instead of the image signal turn the oscillator compensator (5B) to the maximum capacity position (clockwise). From this position slowly turn the compensator counter -clockwise until a second peak is obtained on the output meter. Adjust the compensator for maximum output at this second peak.
If the above procedure is correctly performed, the image signal will be found (much weaker) by turning the signal generator diol 910 KC above the frequency being used on any high frequency ronge.
The aerial padder (5A) must be adjusted to moximum by rolling the tuning condenser. If two signal peaks occur when turning the padder, udiust the

MODEL S-1616
PHILCO RADIO & TELEVISION CORP.
MODEL S-1616 INSTALLING CALL LETTERS IN AUTOMATIC
TUNING DIAL One of the "A" leads on the back of the control head must
be connected so that the current is supplied to operate the automatic control dial. Insert the fuse in the fuse housing in the separate "A" lead (supplied in the radio package), and connect to the "A" lead on the control. The eyelet end of this lead should be connected to the terminal of the Gas Gauge nearest the center of the car.
1-Select and remove from the Call Letter Sheets, the Call Letters of five popular stations in the area in which the radio is to be operated and that comes within the frequency range of the positions on the dial as shown in Illustration for Model S-1616.
2-If the section of the dial in which the tab marked "DIAL" is not at the indicator window, push the Automatic Station Selector until it is in position in the indicator window. The control must be held against the edge of the instrument panel in order to complete the electrical circuit. 3-Push the Automatic Station Selector once more and No. 1 section of the dial will rotate to the front. Insert in this position the call letter tab of the station having the highest kilocycle frequency.
EXAMPLE: The No. 1 position may have the call letters of a station operating on 1400 kilocycles; the No. 2 position, a station operating on 1050 kilocycles. etc.
4-Repeat this procedure until all five call letter tabs se- lected are inserted in the dial in the order of their frequency. Be sure and record the call letters with respect to their posi- tion on the dial for use in setting up the adjusting screws.
5-The control unit should now be completely installed. Remove the trim panel covering the control openings and place the control unit in position in the back of the instrument panel. Insert the bezel windows in the bezel plate, and apply the bezel plate to the front of the panel. The control and bezel are assembled to the instrument with gland nuts. Using the special gland nut wrench provided, tighten the nuts and then apply the two knobs.
SETTING UP THE RECEIVER FOR AUTOMATIC TUNING
Before setting up the Receiver for automatic tuning, it is necessary to synchronize the automatic dial to the Receiver as follows:
Try to tune in a station with the tuning control knob. If no station can be picked up, push the automatic station selec- tor button until the position is found where stations can be tuned in. This is the "DIAL" position. Remove the automatic control cable from the Receiver and again push the automatic station selector button until the word "DIAL" appears in the dial window. The automatic control cable should then be re- placed in its socket on the Receiver and secured with the two self threading screws supplied.
1-Turn the Receiver on and allow it to operate for TWENTY minutes. Remove the cover plate over the automatic tuning adjusting screws. This plate is on the control end of the Receiver and can easily be pried off.
2-Push the automatic station selector button until the word "DIAL" is at the indicator window. Tune in the station whose call letters are in the No. 5 position on the dial (the lowest frequency station) and note the program. Push the automatic selector button five times and this station's call letters will appear at the indicator window.
IMPORTANT-Start adjustments with low frequency screws. 3-With a small screwdriver, turn the No. 5 adjusting screw
(See Illustration for Model S-1616) in the left column to the right or left until the station is tuned in. Now adjust the corresponding screw in the right column until maximum vol- ume is obtained. Make these adjustments carefully, as it may be easy to pass by the loudest point on some stations.
4-Press the automatic station selector button until "DIAL" again is at the indicator window and tune in the station whose call letters are in the No. 4 position on the automatic dial (the next higher frequency). Press the automatic button four times and adjust the number 4 set of adjusting screws to this station.
Repeat this procedure until each of the five pairs of adjust- ing screws has been tuned to its respective station.
It is NECESSARY that the setting of the adjusting screws be repeated to be sure they are properly set so that maximum performance may be had.

SETTING UP THE RECEIVER FOR AUTOMATIC TUNING
& TELEVISION CORP.
1626 and G-1628
Select and remove from the Call Letter Sheets, the Call Letters of five popular stations received in the area in which the radio is to be operated and that come within the frequency range of the adjusting screws as shown in Illustration for Models S-1626, G-1628. Also remove the tab marked "DIAL."
Insert the "DIAL" tab in the slot in the dial which is at the front.
Hold the control against the edge of the instrument panel in order to complete the electrical circuit and push the auto- matic selector button. The dial will rotate one position. Insert in the dial, the call letter tab of the station having the highest frequency in kilocycles. Press the selector button once more and insert the call letters of the station with the next highest frequency in kilocycles.
EXAMPLE-The first position may have the call letters of a station operating on 1400 kilocycles; the second position, a station operating on 1050 kilocycles, etc. Repeat this pro- cedure until all five call letter tabs selected are inserted in the dial in the order of their frequency. Be sure and record the call letters with respect to their position on the dial for use in setting up the adjusting screws.
Before setting up the Receiver for automatic tuning, it is
necessary to synchronize the automatic dial to the Receiver as follows:
Try to tune in a station with the tuning control knob. If no station can be picked up, push the automatic station selec- tor button until the position is found where stations can be tuned in. This is the "DIAL" position. Remove the automatic control cable from the Receiver and again push the automatic station selector button until the word "DIAL" appears in the dial window. The automatic control cable should then be replaced in its socket on the Receiver and secured with the two self threading screws supplied.
1-Turn the Receiver on and allow it to operate for TWENTY minutes. Remove the cover plate over the auto- matic tuning adjusting screws. This plate is on the front of the Receiver and can easily be pried off.
2-Push the automatic station selector button until the word "DIAL" is at the indicator window. Tune in the station whose call letters are in No. 5 position on the dial (the lowest frequency station) and note the program. Push the automatic selector button five times and this station's call letters will
appear at the indicator window.
3-With a small screwdriver, turn the No. 5 adjusting screw (See Illustration for Models S-1626, S-1628) in the left column to the right or left until the station is tuned in. Now
adjust the corresponding screw in the right column until maximum volume is obtained. Make these adjustments care- fully, as it may be easy to pass by the loudest point on some
stations. 4-Press the automatic station selector button until "DIAL"
again is at the indicator window and tune in the station whose
call letters are in the No. 4 position on the automatic dial
(the next higher frequency). Press the automatic button four times and adjust the number 4 set of adjusting screws.
Repeat this procedure until each of the five pairs of adjust- ing screws has been tuned to its respective station.
It is NECESSARY that the setting of the adjusting screws
be repeated to be sure they are properly set so that maximum performance may be had.
Be sure and save the unused call letters, giving them to the owner as they may be needed at some future time if the radio is to be operated in a different area where the local sta- tions are not the same.
If the Stations set up on the Automatic Tuning Dial should at some time tune in at the wrong position, the dial can be easily synchronized to the radio as follows:
1-Find "DIAL" position as explained in the second Para- graph under "Setting up the Receiver for Automatic Tuning."
2-Remove the automatic cable from the socket on the end end of the Receiver.

PHILCO RADIO & TELEVISION CORP.
MODEL S-1726
The antenna and touch tuning station adjustments are accessible from the front of the receiver when the two screws holding the cover plate are removed. On cars equipped with the "Climatizer", it will be necessary to remove the 'screws holding the "Climatizer" control assembly to the lower edge of the instrument panel and drop it down out of the way while making the adjustments.
1-Turn on the radio set and allow it to heat for at least twenty minutes before starting any adjustments.
2-Press the touch control button until the word "DIAL" appears in the "DIAL" window. Tune in a weak station on the manual dial between 1350 and 1500 kilocycles. Now adjust the antenna high frequency compensating screw (See Illus- tration) until maximum volume is obtained.
3-Select five stations within the frequency range shown over each set of adjusting screws (See Illustration). Remove the call letters for these stations from the call letter tab sheet. Remove the top cover of the set; this exposes the plas- tic drum into which the tabs should be inserted. It is impor- tant to insert these tabs in a definite relationship with respect to frequency in order that tuning adjustments can be made properly. Arrange the tabs in the order of frequency from high to low, placing the highest frequency on the drum im- mediately next to the dial tab in a counter clockwise direction. Insert the remaining tabs in the order of freouency in this same counter clockwise direction. If the tabs have been in- serted correctly, it will be found that when the word "DIAL" shows in the window, the next push of the button will place the call letter for the highest frequency station in the window. Each successive push of the control button will place a next lower frequency station in the window until the series is re- peated.
TOUCH CONTROL
4-With "DIAL" showing in the dial window, manually tune in the station to be set up on push button number 1 and identify the program.
5-Press the touch control button once and adjust the left hand screw using the .small end of the special screw driver, until the station identified has been tuned in as accurately as possible. A final adjustment can be made by inserting the large end of the screw driver into the vernier adjusting screw. Careful adjustment of this screw will insure maximum per- formance in areas where reception is poor. NOTE: Stations of the higher frequencies are tuned in by turning the screws to the left or counter clockwise. Lower frequency stations are tuned by turning to the 'right or clockwise. Proceed in like manner with the adjustment of each of the remaining stations in the order of frequency until all five stations selected have been tuned in. Because there is some detuning of the coils (lue to the movements of the cores in adjacent coils, it is necessary to re -check the adjustments again going back from right to left and again re -checking from left to right. This is Impor- tant for accurate reception while driving at a distance from the broadcasting stations.
6-This final re -checking of adjustments should be made in an area of low signal strength in ydur service station or in some known "dead" spot where signals can just barely be heard.
7-Replace the cover plate over the adjusting screws and replace the "Climatiser" controls.
BE SURE AND SAVE THE UNUSED CALL LETTERS, GIVING THEM TO THE OWNER AS THEY MAY BE NEEDED AT SOME FUTURE TIME IF THE RADIO IS TO BE OPERATED IN A DIFFERENT AREA WHERE THE LOCAL STATIONS ARE NOT THE SAME.

5-Press the Rotomatic button until No. 1 appears on the Rotomatic indicator. Now adjust the top screw at position No. 1 until the station selected is brought in with loudest volume. Then adjust the slo.ted hex screw at the bottom until maximum volume is obtained. NOTE: Stations of the higher frequencies are tuned in by turning the screws to the left or counter clockwise. Lower frequency stations are tuned by turning to the right or clockwise.
6-Proceed with setting up the remaining four stations in
the same manner as described under Paragraphs 4 and 5.
7-Because there is some detuning of the coils clue to the movements of the cores in adjacent coils, it is necessary to re-
check the adjustments again going back from Position No. 5
to No. 1 and again rechecking from No. 1 to No. 5. This is
important for accurate reception while driving at a distance from the broadcasting stations.
8-This final rechecking of adjustments should be made in
an area of low signal strength in your service station or in
some known "dead" spot where signals can just barely be
heard. 9-Should the Special Concealed Cowl Aerial be installed
after the original installation, it is absolutely essential that the aerial change -over switch be shifted counter -clockwise and also that all automatic adjustments be made again as described in Paragraphs Nos. 1 to 8. inclusive.

PHILCO RADIO & TELEVISION CORP.
MODEL S-1824 - ADJUSTMENTS All padding adjustments are carefully made at the factory and
ordinarily no readjustments are necessary. However, when read- justments are required, the procedure given below must be followed in detail.
EQUIPMENT- Fully charged heavy duty storage battery or 6 volt power pack, 077 or 177 Philco Signal generator, 027 Philco Vacuum tube voltmeter and set tester or audio output meter, 45-2610 Pad- ding screw driver.
GENERAL-VACUUM TUBE VOLTMETER. The model 027 Vacuum tube voltmeter is an extremely sensitive end accurate test instrument and is recommended for use when aligning and adjust- ing auto radios. Connect the negative (-) terminal of the Vacuum Tube Voltmeter to the high side (ungrounded side) of the volume control. Connect the positive (+) terminal to the radio housing. Connect the "AC" cord to a 110 volt AC socket. Press
the VTVM button and the 10 volt button. Turn the "Set Zero Ohms -- VTVM" control clockwise until a click is heard. Allow the tubes to heat up for a few minutes. Short the 150 meg. VTVM ter- minals and adjust the "Set Zero 150 meg." control until the meter reads zero on the 0-10 range scale (bottom scale). The needle will deflect from left to right.
AUDIO OUTPUT METER. If an audio output meter is used, connect the leads across the voice coil of the speaker. Use the 0-30 volt scale.
With the Radio and signal generator set up for operation at the prescribed frequency, turn the Radio volume control on full and set the signal generator attenuator so that a half scale read- ing is obtained on the meter. The signal in the speaker should be audible but not loud.
The shielding on the generator output lead must be connected to the Radio housing.

P,.-CDEL S-1722 PHILCO RADIO & TELEVISION CORP.
S-1722 INSTALLING CALL LETTERS
Before installing the Receiver, the Call Letters of the sta- tions which are to be tuned in automatically must be inserted in the Automatic Dial. See Illustration,'Models S-1622, S-1722. Select and remove from the Call Letter Sheets, the Call Letters of five popular stations received in the area in which the radio is to be operated and that come within the fre- quency range of the adjusting screws as shown in Illustration Models S-1622, S-1722. Each of the adjusting screws cover the portion of the broadcast band as indicated in Illustration, Models S-1622, S-1722. It is important, therefore, that only such stations be selected as can be tuned in in the range as covered by each screw.
Push the Automatic Station Selector until the word "DIAL" is at the front. This is the starting point. Push the Automatic Station Selector once more and the first position of the dial will be at the front. Insert in this position the call letter tab of the station having the highest frequency in kilocycles. In- sert in back of each tab one of the clear celluloid tabs. Press the Automatic Station Selector button once more and insert the call letters of the station with the next highest frequency in kilocycles in the second position.
a)
CALL LETTER TAB
AUTOMATIC DIAL
Installing Call Letter Tabs
EXAMPLE-The first position may have the call letters of a station operating on 1400 kilocycles; the second position, a station operating on 1050 kilocycles, etc. Repeat this procedure until all five call letter tabs selected are inserted in the dial in the order of their frequency. Be sure and record the call letters with respect to their position on the dial for use in setting up the adjusting screws.
1-Turn the Receiver on and allow it to operate for TWENTY minutes. Remove the cover plate over the automat- ic tuning adjusting screws. This plate is on the front of the Receiver and is removed by removing two screws.
2-Push the Automatic Station Selector button until the word "DIAL' is at the indicator window. Tune in the station whose call letters are in the first position on the dial (the highest frequency station) and note the program. Push the Automatic Selector button once and this station's call letters will appear at the indicator window.

3-With a small screwdriver, turn the No. 1 adjusting screw (See Illustration, Models S-1622, S-1722) in the lower column, to the right or left until this station is tuned in. Now adjust the corresponding screw in the upper column until maximum volume is obtained. Make these adjustments carefully, as it may be easy to pass by the loudest point on some stations.
When adjusting for Automatic Tuning on strong local sta- tions the antenna rod should be all the way down and the adjustments made with the car in a shielded area, such as in a steel constructed building or under a viaduct. This is neces- sary in order to obtain a weak signal so the adjustments can be accurately made.
4-Press the Automatic Station Selector button until "DIAL" again is at the indicator window and tune in the station whose call letters are in the second position on the automatic dial (the next lowest frequency). Press the auto- matic button two times and adjust the number 2 set of ad- justing screws.
Repeat this procedure until each pair of the five pairs of adjusting screws has been tuned to its respective station.
IT IS NECESSARY THAT THE SETTING OF THE AD- JUSTING SCREWS BE REPEATED TO BE SURE THEY ARE PROPERLY SET SO THAT MAXIMUM PERFORM- ANCE MAY BE HAD.
Be -sure and save the unused call letters giving them to the owner as they may be needed at some future time if the radio is to be operated in a different area where the local stations are not the same.

EQUIPMENT- Fully charged heavy duty storage battery or 6 volt power pack, 077 or 177 Philco Signal generator, 027 Philco Vacuum tube voltmeter and set tester or audio output meter, 45-2610 Pad- ding screw driver.
GENERAL-VACUUM TUBE VOLTMETER. The model 027 Vacuum tube voltmeter is an extremely sensitive and accurate test instrument and is recommended for use when aligning and adjust- ing auto radios. Connect the negative (-) terminal of the Vacuum Tube Voltmeter to the high side (ungrounded side) of the volume control. Connect the positive (+) terminal to the radio housing. Connect the "AC" cord to a 110 volt AC socket. Press the VTVM button and the 10 volt button. Turn the "Set Zero Ohms - VTVM" control clockwise until a click is heard. Allow the tubes to heat up for a few minutes. Short the 150 meg. VTVM terminals and adjust the "Set Zero 150 meg." control until the meter reads zero on the 0-10 range scale (bottom scale). The needle will deflect from left to right.
AUDIO OUTPUT METER. If an audio output meter is used, connect the leads across the voice coil of the speaker. Use the 0-30 volt scale.
With the Radio and signal generator set up for operation at the prescribed frequency, turn the Radio volume control on full and set the signal generator attenuator so that a half scale read- ing is obtained on the meter. The signal in the speaker should be audible but not loud.
The shielding on the generator output lead must be connected to the Radio housing.

Make all adjustments for maximum reading on the meter.
NOTE I -Connect the aerial lead Part No. 95-01 I I, to the' aerial receptacle in the radio. Connect a 35 Mmfd. Condenser in series between the signal gnerator and the aerial lead.
NOTE 2-Turn the tuning control clockwise as far as it will go.
NOTE 3 - Rock the tuning control while adjusting the low frequency screw. Tune the control to the signal and adjust the screw for maximum output. Rotate the tuning control back and forth slightly for maximum output. Then readjust the screw for
INSTRUCTIONS FOR SETTING UP THE
Turn on the radio and allow it to operate for twenty minutes
or longer if possible. Press in any automatic button so that it remains engaged.
Then tune in the station desired by turning the small wheel in the
button. The station can be identified by the pointer, which in-
dicates the frequency of the station in Kilocycles. The automatic buttons may be readjusted to any station within the range of the
broadcast band. The automatic buttons may be readjusted to
maximum output. Repeat this procedure until no further improve- ment is noticed.
NOTE 4-When the aerial stage adjustment is made with the Radio installed in the car, the Radio aerial lead must be connected to the car aerial in the usual manner. Connect the signal generator output lead to a wire placed near the car aerial but not connected to it.
NOTE 5-When installing the radio in the car, follow the in- stallation instructions carefully. Tune in a weak broadcast signal between 1200 and 1400 Kilocycles on the control scale. Remove the plug button on the end of the radio and adjust the aerial com- pensator O2 (see Figure 3) for maximum signal.
AUTOMATIC TUNING BUTTONS stations in any sequence desired. However, for convenience in remembering stations, it is recommended that the buttons be set up in the same order that the stations appear across the dial.
CAUTION - All adjustments must be carefully made so that reception can be received best when remote from the broadcasting station. Careless tuning off to one side, even though the signal is
heard, will result in distorted reception.

PHONOGRAPH OPERATION
IT IS IMPORTANT THAT THE SWITCH AT THE REAR OF THE CABINET IS IN THE POSITION CORRESPONDING TO THE TYPE OF LINE CURRENT BEING USED.
The motor is controlled by the automatic stop lever which is at the rear right side of the turntable. The lever protruding from under the turntable on the front side is the speed control. For true reproduction the speed should be adjusted to '78 revolutions per minute. Volume for both, "Phono" and "Radio" is regulated by the same control on the front of the receiver.
The toue control and phono radio switch must be in either of the three -clockwise positions for phonograph operation.
SERVICE NOTES The screws for adjusting both the R.F. and I.F. amplifiers of this re-
ceiver, together with the frequencies at which they should be adjusted, are all pictured on the above diagram. When aligning the I.F. amplifier, the generator must be -connected to the grid of the 12SK7 R.F. tube through a .1 mfd condenser. When aligning the receiver, first align the shortwave band connecting the generator to the antenna post with a 400
ohm resistor. Then align the broadcast band using a .0002 mfd. condenser.
When aligning the loop, the receiver should be in the cabinet with the back in place. The adjusting condenser can be reached through the slot in the lower left hand side of the back.

The locatiin of all adjustments used in re -aligning this receiver, and the frequencies at which these adjustments should be made, are shown zoo,* _s.Q in the accompanying diagram. SOC,re-T
When aligning the I. F. amplifier, the generator must be connected to the grid of the 6SA7 tube through a .1 mfd condenser. When aligning the receiver on the Broadcast Band, connect the generator to the Antenna wire through a .0002 mfd condenser, and on the two short wave bands use a 400 ohm carbon resistor.
ANTENNA
This receiver contains the latest type of self-contained loop aerial and will give excellent results even in distant localities where the signal from the broadcasting státions are faint. However, it may be necessary to turn the cabinet toward the direction of the incoming signal (since most broadcasting stations use the directional antennas), for the best reception from that particular station. For short wave br distant broad- cast band reception, the use of an external antenna isrequired.
When using a. doublet antenna, connect one lead-in wire to terminal "A" at the rear of the chassis, and the other lead-in wire to terminal "D". Remove the connecting link- from terminals "D" and "G" and. connect terminal "G" to a ground such as a cold water pipe or radiator. If an ordinary single wire antenna is used, connect the lead-in wire to Terminal "A" on the rear of the chassis. Leave thé link between "D" and "G" terminals and connect a ground wire under terminal "G". A
doublet antenna kit complete with all accessories, can be purchased from your dealer. Ask to see the "Pilot Antenna Kit".

SERVICE NOTES The location of the screws for adjusting the oscillator, loop and I.F. circuits is in- dicated above. When- aligning this receiver, the "A" and "B" batteries must be in place, and the
set correctly mounted in the cabinet. The signal generator should be connected to the grid of the 1A7GT through a .1 mfd
condenser when aligning the I.F. at 455 kc and when setting the oscillator trimmer at 1400 kc. The loop antenna trimmer and the 600 kc padder should be adjusted, using either e weak gtation or a radiated signal from a signal generator. This receiver may be aligned on either battery or house current.
REAR VIEW OF CABINET SHOWING BATTERIES IN PLACE
BATTERY INSTALLATION
Remove the screws from the back and carefully lift off the back.
When removing the batteries, first unscrew clamps, and then remove battery plugs. Be sure not to pull on the cables, but on the plugs themselves.
Place the new "A" and "B" batteries in position shown on diagram below and replace clamps in position shown below.
The black and white cable, coming from the chassis, has a 2 -prong plug which. is then plugged into the double "A" battery. The red and black cable has two 3 -prong plugs, both of which are plugged into the -'B" batteries. It is optional which plug goes into eithér "a" 'battery.

ANTENNA This receiver contains the latest type of self-contained loop aerial
and will give excellent results even in distant localities where the signal from the broadcasting stations are faint. However, it may be necessary to turn the cabinet toward the direction of the incoming signal (since most broadcasting stations use the directional antennas), for the best reception from that particular station. For short wave or distant broad- cast band reception, the use of an external antenna is required.
When using a doublet antenna, connect one lead-in wire to terminal "A" at the rear of the chassis, and the other lead-in wire to terminal "D". Remove the connecting link from terminals "D" and "G" and connect terminal "G" to a ground such as a cold water pipe or radiator. If an ordinary single wire antenna is used, connect the lead-in wire to Terminal "A" on the rear of the chassis. Leave the link between "D" and "G" terminals and connect a ground wire under terminal "G".

When aligning the I.F. amplifier, the generator must be connected to the
grid of the 6SA7 tube through a .1 mfd condenser. When aligning the receiver on
the Broadcast Band, connect the generator to the Antenna wire through a .0002 mfd
condenser, and on the seven short wave bands through a 400 ohm carbon resistor.
In general it is not recommended to re -align the bandspread ooils unless it
is definitely necessary. If re -aligning is found to be necessary, take off the
dial pan be removing the five screws, as indioated on the diagram.
First adjust the oscillator iron core to make the pointer correspond with the
calibration mark. Then adjust the antenna iron core for maximum output. The sig-
nal generator must be accurate within 5 kc on each band,and the use of a calibrating
crystal oscillator is recommended. Otherwise a broadcast signal of known frequency
may be used. In this receiver the oscillator frequency in higher than the signal frequency
on,the broadcast band and lower on the seven other bands.
This Pilot Superheterodyne Receiver has 10 tubes and a Cathode: Ray Tuning Beacon, and operates an either an Alternating or Direct Current power supply.

To make the installation:
RCA MFG. CO.. INC.
1. See that the power control on the phonograph is
turned off.
2. Loosen the pickup arm at its base mounting so that it
can be lifted complete and turned over. The pickup
arm may be removed from its location in the cabinet
to the extent permitted by the connecting wires. The
support remains attached to the motorboard.
The arms A, D and E, Figure 2, may be disengaged
from their supporting pivots by compressing the two
hinge springs at the rear of the arms.
Remove the pickup arms B and C by pushing' out
the pin at the rear of the arm. Then pull the pickup
forward off the pickup arm support.
3. With pickup arm turned over in a convenient position, unsolder the two leads and loosen the two screws hold-
ing the present pickup cartridge in the pickup arm
head. Then remove the cartridge complete leaving the
loose leads clamped in the arm.
The arm A, Figure 2 may contain a lead weight
which will obstruct ready installation of the new pickup
cartridge. The weight may be removed by (a) scoring
the bracket at its bend with diagonal cutters and bend-
ing until it breaks or (b) drilling several small holes in
the bracket at the bend and bending until it breaks.
It is preferable and recommended to use a new arm,
Stock No. 9951, List Price $0.90.
4. Place the plate, supplied in the kit, in the pickup arm
head with the two irregularly shaped holes in the plate
matching with the screw holes in the arm. Attach the
plate loosely in position with the two short binder head
screws supplied in the kit, placing a washer above and
below the plate on each screw.
5. Solder the two leads to the strip terminals on the Magic
Tone Cell, being sure that the shield lead is attached
to the ground terminal-the one on the right when
viewed facing the front end, sapphire downwards- See Figures 2 and 3.
PICKUP AXIS
R-815
The soldering operation must be performed as quickly
as possible so as not to heat the crystal.
6. Place the Magic Tone Cell in position, sapphire out-
ward, with screw holes matched with the correct pair
of threaded holes in the plate. Before fastening the
Magic Tone Cell to the mounting plate, hold it in posi-
tion and adjust the plate so as to permit mounting with
playing point position, pickup axis and tracking the
same as for the cartridge removed.
Tighten up the plate screws and then assemble the
Magic Tone Cell in place using the two long fillister
head screws supplied, placing the spacers on the screws
between the cartridge and the mounting plate.
Note: Be careful not to bend the sapphire support
wire, and be sure that the lead connections do not
short to the arm, spacers or plate.
7. On pickup with a comparatively large hole on top for
needle insertion, insert the plug button, supplied in the
kit, securely in the hole.
8. Carefully reassemble the pickup arm and check its
movement, making any necessary adjustments for cor-
rect operation as indicated in later paragraphs.
In case adjustment for "set down" and "height" is
necessary it may be advisable to refer to service notes
for the particular record player.
It may be necessary to weaken the tension on the
feed -in spring on some mechanisms, in order to prevent
the pickup from kicking -in too hard at the beginning
of each record. Reduce tension by lengthening the
spring or in most cases cut and remove the spring.
On certain phonographs it may be desirable to adjust
the compensation in the audio circuit for best record
reproduction.

Mechanical Adjustments
On all models the sapphire height above the motorboard should be checked. The sapphire point must enter the record groove and bear prop- erly on the record. It must not strike or scrape on the motorboard as it may be damaged.
Swing out the pickup over the motor - board and adjust the sapphire height by carefully bending the pickup arm support bracket so that the sapphire point is 1/8 inch above the motor - board. The pickup should then- oper- ate properly throughout the playing cycle for both automatic and manual playing.
Any other necessary mechanical ad- justments should be made in accord- ance with the Service Notes for the particular model.

The information on the above key models will serve as
a guide to cover the installation on other RCA Models of 1938 and later manufacture.
General Information on Compensation For Pickup Circuits 1. The pickup should be terminated or loaded in accordance with the information given in the preceding table. 2. Decreasing shunt resistance across pickup circuit decreases bass response and increasing shunt resistance across pickup cir- cuit increases bass response. 3. Examples of compensation adjustments.
Cl
Circuit I-Increasing R1 increases low frequency response. Increasing Cl increases high frequency response.
R3 Increasing value of R3 with respect to total value of R2 plus R3 increases the output.

Circuit III-Increasing R1 increases low frequency response. Increasing R2 increases high frequency response. Increasing value of Cl with respect to total value of Cl plus C2 increases the output.
Operating Tests
Mechanical-The pickup should be tested for its corn- plete operating performance. On record changing instru- ments both a full stack of records and a single record should be used in the test.
Checks should be made for:- a. Correct landing on 10 inch and 12 inch records.
b. Correct tripping on 10 inch and 12 inch records.
c. Correct elevation of pickup arm.
d. See that neither sapphire guard nor rear end of pickup tends to "drag" on the record when a full stock of records is being used. Seat pickup deeper into arm if necessary.
Refer to the service notes for the particular model in all cases requiring readjustment.
2. Electrical-It should be remembered that the output of the Magic Tone Cell is inherently lower than that of former crystal pickups, thus involving a lower reserve volume. The volume control on the instrument must there- fore be further advanced than before, and the full volume position may occasionally be necessary. The best operating position should be checked on several records.
a. Hum-In cases of excessive hum, examine to see that shielding is intact and receiver circuits are nor, mal. Make any necessary corrections.
b. Rumble or Howl-Excessive rumble or howl may be remedied by examining motor and motorboard mountings for flexibility and making any necessary corrections or improvements.

Caution-Never bend the sapphire support wire. The nut on the sapphire holder assembly is locked by a
light cement (such as Glyptal). Extreme care should be used when loosening the nut so that the twisting motion does not break the crystal.
Remove the two screws holding the sapphire guard in place and take the guard off. Remove the small nut and washer on the threaded shaft of the sapphire holder and push the shaft through the hole in the viscoloid until the sapphire holder assembly comes free.
Insert threaded shaft of replacement sapphire holder through viscoloid and replace the washer and nut. Make

sure that the flat sides of the shaft are firmly in place in the clamp and then tighten the nut very carefully so as not to strip the threads nor break the crystal. Replace the sapphire guard, positioning it by means of the oversize screw slots. Make certain that the sapphire and its supporting wire are centered in the guard. Tighten the guard screws.
Before using, check to see that the sapphire projects far enough beyond the guard so that the guard will not strike the record. If necessary, bend the guard a little. Apply a
drop of light cement (such as Glyptal) to the sapphire nut holder.

Tone Arm Stop Bracket:
On 2nd production RP -158 and RP -160, a stop bracket has been added to the top of the motorboard to restrain the tone arm. It is mounted by means of the same screw, lock - washer, and nut used to mount the pickup shorting switch. Where difficulty is experi- enced with excessive movement of the tone arm on 1st production mechanisms, this bracket may be added as shown. The bracket is Stock No. 39832. RP -158, -160
To Repeat One Record:
When checking RP -158 and -160 record changers for landing and tripping action, it is possible to play one record repeatedly by simply placing a weight on the rear record post. A small pipe nipple that fits over the top of the post is satisfactory.

To Play One Record Continuously:
It is possible to play one record cqntinuously on the,RP-151 by stretching a 3h -in. or 4 -in. rubber band across the mechanism, as shown, to prevent the record dropping through the motorboard.
The continuous playing of a record in this manner is handy when the record changer is being serviced, especially after the separator knives have been checked and tested, and it is desired to allow the changer to run on the shop bench without attention.

"KNOCKED -DOWN" VOICE
COIL AND CONE Installation Instructions:
To simplify cone replacement in certain speakers, the cone and voice coil are supplied as two separate units : (1) The voice coil and support, (2) The cone diaphragm.
General Procedure (a) Cement voice -coil support to the speaker
using centering gauge or speaker shims. (b) Solder voice -coil leads. (c) Put cone in place, cementing around rim
of speaker frame. (d) Cement junction of cone and voice coil.
Detailed Instructions (a) Remove old cone and voice coil. Protect
air gap with scotch tape. Clean off all paper and cement.
(b) Apply a ring of cement (Duco Household) on top plate.
(c) ,Insert centering gauge in new voice coil, handle first, from the winding end.
(d) Remove scotch tape from gap. Insert voice coil and gauge in gap with leads in cor- rect position for soldering. Press rim of voice coil support into the cement.
ABSORPTION WAVE TRAP For Loop Receivers:
Interference and cross modulation due to the presence of a strong local broadcast station is seldom experienced on loop -type receivers be- cause the signal pickup is much less on a loop
'than on an antenna. - However in rare cases where such interference is encountered, it can generally be eliminated by using an absorption -type wave trap, loosely coupled to the loop on the receiver, as shown in accompanying sketch, and tuned to the fre- quency of the interfering station.
A good absorption trap can be matte with a small loop like that used in Model BP -10 "Personal" radio. Fasten a two -section mica trimmer (salvaged from a discarded IF trans- former) on the small loop. Connect the trim- mer across the terminals of the small loop. Use one trimmer, or both in parallel, depending on whether the interfering station is at the high or low end of the broadcast band.
Tune the receiver to the frequency of the interfering station, place the trap near the re- ceiver loop, and adjust the trap trimmer(s) to resonance, indicated by a sharp dip in signal strength. Use smaller or larger capacity trim- mers if required to reach resonance.
Check to see if the particular interference effects have been eliminated. Adjust the posi- tion of the trap to secure closer coupling if necessary to further increase signal absorption. Avoid over coupling. Fasten the trap in the desired position on the receiver loop.
BP -10 LOOP USED AS ABSORPTION WAVE TRAP
On a loop receiver, interference front a strong local broadcast station can be reduced by using an absorption loop,
tuned to the interfering station, and loosely coupled to the
receiver loop.

Certain replacement cones are supplied "knocked -down" in two pieces-(1) The
voice coil and centering support. (2) The cone diaphragm.
VOICE COIL IMPEDANCE And DC Resistance:
In servicing RCA radio loudspeakers, it is helpful to know that the DC resistance of the voice coil is approximately 10 percent less than the impedance at 400 cycles.
For example, a speaker with a rated voice - coil impedance of 2.2 ohms at 400 cycles will measure about 2 ohms DC resistance.
Radio storage battery can be charged on a DC farm -lighting outfit.
BATTERY COMPLEMENT
(g) Allow cement to dry on cone rim and voice - coil support. Then run a ring of cement around the junction of the cone and voice coil, being careful the cement does not run inside voice coil.
(h) After cement at junction has dried, remove gauge, using a rotary motion.
(i) Cement large cardboard gasket in place. Set the speaker in inverted position on a flat surface until gasket is dry. Cement dust cap on cone center.

RCA SCHEMATICS
Switch Positions:
Practically all of the larger RCA receivers have decals on the cabinet (or other means) to indicate the function of each position on the more complicated switches. In cases where only the chassis is brought in for service, the corresponding information about controls is given in a knob drawing printed in the Service Note.
For example, the accompanying schematic shows the radio-phono-tcne control switch cir- cuit in Model V-135, drawn as usual in the extreme counter -clockwise position. The knob view shows the function of each position:
(1) "Off" (counter -clockwise).
(2) Radio-mellow tone.
(3) Radio-full tone.
(4) Phono-mellow tone.
(5) Phono-full tone (clockwise).
As a general rule, on RCA receivers clock- wise rotation of a control produces an increase. Thus on a range switch, the lowest -frequency hand is counter -clockwise, and the highest -fre- quency band is clockwise. On tone controls, the narrowest audio range or deepest tone is counter -clockwise. The widest audio range or highest tone is clockwise.

STOCK Nó. 160 CRO Vertical "Bounce":
The 160 'oscillograph has extremely good lowfrequency response, passing a 4 -cycle square wave with good fidelity. It is possible to encounter instances in which a line -voltage meter, due to its inertia will indicate little or no v-ariatjtyt of voltage, whereas the oscillo - graph will exhibit noticeable vertical "bounce" due to line -voltage fluctuations.
If a cústomer desires to retain the normal lowfraquency response of the 160 and has a power lite which varies in voltage appreciably, it is necessary to provide voltage regulation, such as TMV-173 voltage regulator. How- ever, if the extreme response of the 160 is superfluous for the particular application in mind it can readily be reduced, affording a re- duction of the "bounce" to an unobjectionable value. This is accomplished by removing the present coupling condenser, C-20, and substi- tuting a 0.05 mfd. 400 -volt condenser. The re- sponse is then down a few percent with a 15. - cycle sine. wave input.
(The 160B incorporates filtering circuits to eliminate vertical "bounce.")
For applications in which it is desired to con- nect directly '12. the cathode ray tube deflecting plates, such the observation of a modulated RF envelope 'from a transmitter, it is possible to completely eliminate the vertical "bounce" by merely disconnecting either side of the coup- ling capacitor, C-23.

HOLDER FOR RECORD CHANGER
Essential in Servicing: In servicing an automatic record changer, it,
is essential to have some kind of a holder or stand to support the mechanism in a level posi- tion at a convenient height above the work table to permit easy access to all parts under the motorboard.
Adjustable stands can be purchased, or as- sembled from pipe fittings as shown in the accompanying sketch.
The simplest and cheapest type of holder is made by using legs that screw into the motor - board -mounting -screw sockets. Such legs can be made from pipe fittings or from threaded rods as shown in the sketches. One end of each leg has a i-20 thread to accommodate most RCA changers, and the other end has a 5/16-18 thread to accommodate the RP -151 mechanism.

RP -152D, -153, QU7 Automatic Motor Switch:
Some models of RCA automatic record changers incorporate a switch that acts to shut off the motor when the pickup needle is 13 inches from the spindle, and also when the pickup is moved out to its rest position.
The original switch, Stock No. 36529, is superseded by an improved switch, Stock No. 38995. When installing- the new switch, re- move the angle bracket that is used between the motor board and the original switch.
VHR.-202, -207, -307, -407 Crystal Pickup is No. 37158
In the Service Data for these home -recording models, the pickup cartridge is incorrectly listed as No. 33905. The correct Stock Number is 37158. This correction should also be noted in the tabulation on page 5 of "Supplementary Information No. 5."
The label reproduced above is fastened to the record changer in Models V-215, -219, -221, and -225.
These mechanisms are designed for com- pletely automatic operation on a stack of rec- ords or on a single record.
Customers sñoutd be instructed to use the START -REJECT button and not to handle the tone arm.
Note: If item 13 is not obtainable, change item 2 to 2I -in. nipples, and drill 5/16 -in. holes close to one end to accommodate the motor- z_ board mounting bolts.

The original bronze trip -pawl spring, Stock No. 38362, is no longer available. When this spring requires replacement, due to loss or irreparable damage, it is necessary to install either a new steel spring, Stock No. 39961, in accordance with instructions given below, or else install a complete new trip lever assembly which employs the steel spring.
In RP -151, the new trip lever, trip pawl, and steel spring assembly is Stock No. 38561
In RP -158, -160, and -162, the new trip lever, trip pawl, and steel spring assembly is Stock No. 38632.
The new lever and spring assemblies will be supplied on orders for the original assemblies.
Installing Steel Spring No. 39961 on Trip Lever: 1. Drill a 3/32 -inch hole in lever as shown. 2. Cut off the tab that was used to anchor the

REVISED RATCHET LEVER
In RP -158, -160, and -162, continuous trip- ping can be- caused by failure of the ratchet lever to bldck the drive cam pawl at comple- tion of a change cycle.
This has been corrected by doubling the thickness of the end of the ratchet lever so that it presents a broader face to the edge of the drive cam pawl. The lever with double thick- ness is carried under the same Stock Number (38656) as the original lever, which it super- sedes.

The following Stock Numbers for crystal - and -sapphire assemblies supersede all previous listings:
RCA MFG. CO., INC.
Zinc -cased crystals have letters "ZN" cast in the metal.
Use only zinc -cased crystal No. 39550 for RP -160. This can not be used in RP -151.
Do not replace complete pickup where sap- phire only requires replacement.

RP -160 Sapphire Pressure:
The correct sapphire pressure in RP -160 is approximately 13 ounces. The pressure is governed by a spring inside the end of the pickup arm. Owing to the fact that' both aluminum and zinc castings (with difference in weight) have been used for the arm and the crystyj, and also that only the zinc crystal (Stock No. 39550) is supplied for replacement,
it is necessary to check the sapphire pressure whenever either the crystal or the arm is re- placed.
The zinc arm is identified by the letters "ZN" after the drawing number inside the arm.
The zinc crystal is identified by the letters "ZN" moulded at the rear end of the cartridge.
The various combinations arc tabulated be- low, along with the Stock, Numbers of pivot arms and springs involved.

60 TO 50 CYCLE CONVERSION For Rim -Drive Phono Motors:
(These instructions supersede all 'past issues, covering the use of shrunk sleeves.)
A spring sleeve is used to increase the di- ameter of the motor drive spindle, to compen- sate for the slower speed of the motor when used on a 50 cycle line.
Spring sleeves are available for the following
models which comprise most of the motors using spindle drive manufactured to date.'
To apply the spring -sleeve to the motor spin- dle, lock the rotor matually and press spring gently over end of spindle, twisting the free end of spring counter -clockwise (to unwind coil) until following end of spring is flush with end of spindle.
The ends of spring should not protrude, and all coils should be close together, allowing a flat even surface on the motor spindle to con tact the rubber drive.

IMPROVED TONE ARM RETURN
LEVER
Stock No. 39751
The tone arm return lever in RP -158, -160, -162, has been revised to incorporate two im- portant improvements:
(1) A cam to adjust landing position on 12 - inch records.
(2) A positive -acting feed -in lever and spring. (This pushes the tone arm in toward the music grooves after the sapphire has landed - on the record.)
This revised lever, Stock No. 39751, super- sedes the original lever, Stock No. 38618.
12 -inch Landing Adjustment: When adjusting a mechanism that has this
revised lever, make the 10 -inch landing adjust- ment in the usual manner as specified in the service notes. Then check landing on a 12 -inch record and adjust the cam if necessary. The correct landing position for 12 -inch records is 53 inches from the sapphire to the nearest side of the spindle.
Feed -in Spring Adjustment: The feed -in spring (Stock No. 39752) is
hooked in one hole on a bracket that has three spaced holes to permit coarse adjustment of feed -in tension. Fine adjustment can be obtained by bending the bracket.

'Stock No. 39751 tone arm return lever has a cam to adjust 12 -inch landing position,
and a positive acting feed -in mecha- nism. The feed -in tension can be adjusted by hooking the spring
in a different hole on the bracket, and by bending
the bracket. RP -158, RP -162
Tone -Arm Resonance:
Chatter at frequencies near 2,500 cycles on some 1st production RP -158 or RP -162 mech- anisms is caused by tone -arm resonance which can be eliminated by inserting a block of vis- coloid (t in. x t in. x 3/16 in.) in the arm as shown. The viscoloid block is No. 39949.

Cathode Ray Alignment is the preferable method. Connections for the oscillograph are shown in the diagram.
Output Meter Alignment.-If this method is used, connect the meter across the voice coil and turn the receiver volume control to maximum.
Test Oscillator.-For all alignment operations, connect the low side of the test oscillator to the receiver chassis, and keep the output as low as possible to avoid AVC action.
Electronic Voltmeter.-The electronic voltmeter in the Chanalyst or VoltOhmyst provides an unexcelled output indicator. It should be connected to the AVC bus.
Pre -Setting Dial.-With gang condenser in full mesh, the pointer should be adjusted so that it is horizontal.

Hum Modulation on Model 25BT9 When Using CV -42 "Electrifier."
The following changes should be made in cases where hum modula- tion is experienced when operating Model 25BT3 from a CV -42
electrifier power unit. It is not necessary to remove the chassis from the cabinet to make these changes.
(1) Connect a 220 mmfd. molded mica capacitor in series with the blue antenna lead as shown.
(2) Disconnect the black ground lead and C19 from the bottom lug on the antenna coil. Connect a jumper from this lug to chassis. Connect the black ground lead to C19 and tape the joint.

The station push buttons connect to separate magnetite -core oscil- lator coils and separate antenna trimmers which must be adjusted for the desired stations. Use an insulated screwdriver or alignment tool such as RCA Stock No. 31031. Allow at least five minutes warm- up period before making adjustments.
In the event that the receiver is to be used with an external an- tenna use one or two feet of wire (as an antenna) to ensure sharp

PUSH-BUTTON RANGES One station between approximately 540-1,100 kc One station between approximately 610-1,250 kc Two stations between approximately 750-1,420 kc One station between approximately 950-1,560 kc
Adjustment peaking during the final adjustment procedure. For loop operation, the link should be strapped across terminals on back of set. In either case the procedure is as follows:
1. Make a list of the desired stations, arranged in order from low to high frequencies.
2. Turn the range selector to "A" band, and manually tune in the first station on the list.
3. Turn range selector to "PB" position, push in station button No. 1 (extreme left). Then adjust the No. 1 oscillator core to receive the station.
4. After oscillator core is set correctly, adjust No. 1 antenna trimmer for maximum output.
Clockwise adjustment of cores and trimmers tunes the circuits to lower frequencies.
5. Adjust for each of the remaining stations in the same manner.
8. Make a final careful adjustment of the oscillator cores and an- tenna trimmers.
On the 950 to 1,560 kc push-button, the higher frequency stations may be received with L24 either in or out (oscillator frequency either 455 kc below or 455 kc above the station frequency). The adjust- ment with this core in its out position (oscillator frequency 455 kc above the station frequency) is the correct one.
Alignment Procedure Test Oscillator.-For all alignment operations, keep the output as
low as possible to avoid a.v.c. action.
Output Meter Alignment.-If this method is used, connect the meter across the voice coil, and turn the receiver volume control to maximum.
Calibration Scale.-The glass tuning dial may be easily removed from the cabinet and temporarily attached to the dial backing plate for quick reference during alignment.
Power Supply Polarity.-For operation on d -c, the power plug must be inserted in the outlet for correct polarity. If the set does not function, reverse the plug. On a -c, reversal of the plug may reduce hum.

Test-Oscillator.-For all alignment operations, connect the low side of the test -oscillator to the receiver chassis, and keep the output as
low as possible to avoid a -v -c action. Electronic Voltmeter.-The electronic voltmeter in the Chanalyst or
VoltOhmyst provides an unexcelled output indicator. It should lie connected to the AVC bus, and the test -oscillator output adjusted to produce several volts of AVC.
Calibration for Alignment.-The dial calibration for alignment pur- poses can be set up in two ways:
1. The dial may he very easily removed from the cabinet. The condenser plates should then be turned into full mesh, the pointer adjusted to the scratch at the left end of the dial back- ing plate, and the dial placed on the frame so that its extreme left calibration mark coincides with the pointer. The dial may be held in place with scotch tape. In this manner the actual receiver dial is used for alignment. When alignment is finished, the scale should lie replaced.
2. A calibration scale is attached to the tuning drum. The correct setting of the gang, in degrees, for each alignment frequency is given in the alignment table. Check the position of the drum, making sure that the 0 degree scale mark is horizontal with the gang in full mesh.
Pointer for Calibration Scale.-If method (2) is used, improvise a
pointer for the calibration scale by fastening a piece of wire to the chassis, and bend the wire so that it points to the O degree mark un the calibration scale when the plates are fully meshed.

Cathode -Ray Alignment is the preferable method. Connections for the oscillograph are shown in the schematic diagram.
Output Meter Alignment.-If this method is used, connect the meter across the voice coil, and turn the receiver volume control to maximum.
External Antenna.-For best reception on "C" band with an out- side antenna, adjust C2 for peak output on a station in the 31 -meter
band.

Thermal relay cuts in the dial lamps after the set warms up.- This set incorporates a thermal relay to control the dial lamps. When
the set is "off," the relay contacts are closed. This shorts out the
two lamps. When the set is turned "on," the heater current flows
through the relay element R24. This heats up and causes the relay
contacts to open, permitting the heater current to flow through the
two dial lamps and light them. In normal operation, the lamps. light
about a half -minute after the set is turned on.

Alignment Output Meter Alignment.-Connect the meter across the voice coil,
and turn the receiver volume control to maximum.
Test-Oscillator.-Connect the low side of the test -oscillator to the receiver chassis, through a .01 mid. capacitor, and keep the output as low as possible.
Antenna.-The set is equipped with a built-in loop antenna. If an outdoor antenna is used, it may be connected to the `ANT" terminal on rear of cabinet. It should not be longer than 100 feet, including lead-in. If it is longer, connect a 100 to 200 mmf. capacitor in series with the lead-in.
Power -Supply Polarity.-For operation on d -c, the power plug must be inserted in the outlet for correct polarity. if the set does not function, reverse the plug. On a -c, reversal of the plug may re-
duce hum.
Phono Attachment.-A jack is provided on the rear of cabinet for connecting a Phono Attachment into the audio -amplifying cir- cuit. The cable from the Phono Attachment should be terminated in a Stock No. 31048 plug to fit the jack.
Dial Pointer Adjustment.-The dial pointer should be set at the left hand end dial marks, with the gang in full mesh.

Thermal relay cuts in the dial lamps after the set warms up.- This set incorporates a thermal relay to control the dial lamps. When the set is "off," the relay contacts are closed. This shorts out the two lamps. When the set is turned "on," the heater current flows through the relay element R24. This heats up and causes the relay contacts to open, permitting the heater current to flow through the two dial lamps and light them. In normal operation, the lamps light about a
half -minute after the set is turned on.

Push Button
The station push buttons connect to separate magnet -te -core oscil- lator coils and separate antenna trimmers which must be adjusted for the desired stations. Use an insulated screwdriver or a ignment tool "such as RCA Stock No. 31031. Allow at least five minutes warm-up period before making adjustments.
In the event that the receiver is to be used with an external an-
tenna use one or two feet of wire (as an antenna) to ensure sharp p,raking during the final adjustment procedure. 1. Make a list of the desired stations, arranged in order from low
to high frequencies.
Alignment Output Meter Alignment.-Connect the meter across the voice coil,
and turn the receiver volume control to maximum.
Test-Oscillator.-Connect the low side of the test -oscillator to the receiver chassis, through a .01 mfd., capacitor, and keep the output as low as possible.
Antenna.-The set is equipped with a built-in loop antenna. If an outdoor antenna is used, it may be connected to the "ANT" terminal on rear of cabinet. It should not be lor.ger than 100 feet, including lead-in. 1f it is longer, connect a 100 to 200 mmf. capacitor in series with the lead-in.
Power -Supply Polarity.-For operation on d -c, the power plug must he inserted in the outlet for correct polarity. If the set does not function, reverse the plug. On a -c, reversal of the plug may re- duce hum.
Phono Attachment.-A jack is provided on the rear of cabinet for connecting a Phono Attachment into the audio -amplifying circuit. The cable from the Phono Attachment should be terminated in a Stock No. 31048 plug to fit the jack.
Dial Pointer Adjustment.-The dial pointer should be set at the left-hand end dial marks, with the gang in full mesh.

Adjustment 2. Turn the range selector to "A" band, and manually tune in the
first station on the list.
3. After turning range selector to "PB" position, push in station button No. 1 (extreme left). Then adjust the No. 1 oscillator core to receive the station. It may be necessary to maintain ap- proximate tracking between antenna and oscillator to receive weak stations.
4. After oscillator core is adjusted properly, adjust antenna trimmer No. 1 for maximum output.
Clockwise adjustment of cores and trimmers tunes the circuit. to lower frequencies.
5. Adjust for each of the five remaining stations in the same manner.
6. Make a final careful adjustment of the oscillator cores and antenna trimmers.
On push-button No. 5, the higher frequency stations may be obtained with the oscillator core No. 5 either in or out. (Oscillator frequency either 455 kc below or above the signal.) The out position should be used so the oscillator is 455 kc above the signal.

Calibration Scale on Indicator -Drive -Cord Drum-The tuning dial is fastened in the cabinet and cannot be used for reference during alignment, therefore a calibration scale is attached to the indicator - drive -cord drum which is mounted on the shaft of the gang condenser. The setting of the gang condenser is read on this scale, which is calibrated in degrees. The correct setting of the gang in degrees, for each alignment frequency, is given in the alignment table.
As the first step in R.F. alignment, check the position of the drum. The 135° mark on the drum scale must be vertical, and directly over the center of the gang -condenser shaft when the plates are in minimum capacity position. The drum is held to the shaft by means of plastic cement which must be securely fastened when the drum is in the correct position.
To determine the corresponding frequency for any setting of the calibration scales, refer to the accompanying drawing which shows the dial with 0-180° calibration scales drawn at top and bottom.
Pointer for Calibration Scale.-Improvise a pointer for the cali- bration scale by fastening a piece of wire to the gang -condenser frame, and bend the wire so that it points to the "0" mark on the calibration scale when the plates are fully meshed.
Dial -Indicator Adjustment. - After fastening the chassis in the cabinet, attach the dial indicator to the drive cable with indicator at the 540 kc mark, and gang condenser fully meshed. The indicator has a spring clip for attachment to the cable,

Phasing Speakers in 291(2 For correct tone, it is ESSENTIAL that the two speakers operate
"in phase." so that the two cones move In and out together. It is necessary to check the phasing whenever a new speaker, cone,
field coil, or output transformer is installed, or whenever the speaker connections are altered in any way.
The recommended procedure is as follows: 1. Hook up a "phase checker," using headphones or PM speaker
units as shown. Connect the checker to an audio amplifier that has an output meter. (The audio channel in the Chanalyst is excellent for this purpose.)
2. Feed a 400 -cycle modulated signal into the receiver. Turn volume up to medium. Hold both units of the checker in front of the large speaker in -set- Throw the toggle switch to each position and note which position gives maximum output on meter. Mark this position of the switch "in phase." Mark the other position "out of phase."
3. Place one unit of the phase checker in front of each speaker in the set. Throw the toggle switch to each position and leave it at the position that gives greatest output on the meter. Note the switch marking for this position. If it says "in phase," the set speakers are correctly phased. If it says "out of phase," reverse the leads to the voice -coil terminals of the small speaker in the receiver.

Phasing Speakers in Model 55X.- For correct sound quality, it is ESSENTIAL that the cones
of the two loudspeakers move in and out together. To check the phasing, connect a 111 -volt dry cell across the
secondary of the output transformer and observe, by sight or feel, whether the two cones move in the same direction. If one moves in while the other moves out, reverse the external connections to the voice coil of the permanent -magnet speaker.

Pre -Setting Dial.-With gang condenser in full mesh, the pointer should be adjusted so that it is vertical.
Power -Supply Polarity.-For operation on d -c, the power plug must be inserted in the outlet for correct polarity. If the set does not function, reverse the plug. On a -c, reversal of the plug may -
reduce hum.

Precautions in Handling Kinescopes The Kinescope bulb encloses a high vacuum and, due to
its large surface area, is subjected to considerable air pres- sure. For these reasons, Kinescopes must be handled with more care than ordinary receiving tubes.
The large end of the Kinescope bulb - particularly that part at the rim of the viewing surface-must not be struck, scratched or subjected to more than moderate pressure at any time If the tube sticks, or fails to slip into its socket or de- flecting yoke smoothly, investigate and remove the cause of trouble. Do not force the tube.
All RCA Kinescopes are shipped in special cartons and should always be left in the cartons until ready for installa- tion in the receiver. Keep the carton for future use.
The RCA -1803-P4 (12 -inch) Kinescope is equipped with a protective lid and shield. Do not at any time remove the close -fitting cone -shaped section of the protective shield from the Kinescope. This section should be installed with the tube in the cabinet and is designed to protect the user while handling the glass bulb.
CAUTION: Do not open the shipping carton, install, re- move, or handle the Kinescope in any manner, unless shatter- proof goggles and heavy gloves ape worn. People not so equipped should be kept away while handling Kinescopes. Keep Kinescope away from the body while handling.

RCA MFG. CO., INC. The finest television receiver built may be said to be only
as good as the antenna design and installation. It is therefore important to use a correctly designed antenna, and use care in its installation.
The RCA Double Dipole Antenna, Stock No. 9871, is recommended for use with these receivers. Both this antenna and the "V" antenna described below are especially designed
for a sufficient broad frequency response to cover the con- templated television spectrum with good efficiency and are 'therefore superior to a single Dipole type antenna.
When greater signal pickup, or where a shielding effect from noise sources or image reflections are desired, a reflector assembly, Stock No. 9872, may be added to the Stock No. 9871 Antenna to obtain an improved signal-to-noise ratio.
The RCA Double "V" Wire Type Television Antenna is an alternative type of antenna designed for television sight and sound reception. Two points of support are necessary. It serves adequately in suburban areas, but may not be suffi- ciently flexible in congested city areas where bad reflections and interference are encountered. Antenna Installation.
In most cases, the antenna should not be installed per- manently on the apartment or residence roof until the quality of the picture reception has been observed on a Television receiver. A temporary transmission line can be run between receiver and the antenna allowing sufficient slack to permit moving the antenna. Then, with a telephone system con- necting an observer at the receiver and an assistant on the roof to find an antenna location, the anténna can be posi- tioned to give the most satisfactory results on the received signal. A shift of only a few feet in antenna position or di- rection may effect a tremendous difference in picture re- ception.
Whenever possible, the antenna location should be chosen or erected so the antenna is not only broadside to the trans- mitter but removed as far as possible from highways, hos- pitals and doctors' offices and similar sources of interference. Auto ignition and diathermy apparatus may cause noise in- terference spoiling the picture.
In mounting any antenna, care must be taken to keep the antenna rods or pickup wires proper at least i/4 wave length (at least 6 feet) away from other antennas, metal roofs and gutters or metal objects. Under certain extremely unusual conditions, it may be possible to rotate or position the an- tenna so it receives the cleanest picture over a reflected path. If such is the case, the antenna should be so positioned. However, such a position may give variable results as the nature of reflecting surfaces may vary with weather condi- tions, as a wet surface has been known to have different re- flecting characteristics than a dry surface.
In short, a television receiving antenna and its installation must conform to much higher standards than an antenna for reception of International Short Wave and Standard Broad- cast signals because:
(1) Intervening obstacles have a pronounced shielding effect on the ultra -high frequency waves producing low in- tensity signals. Severe trouble with multi -path transmissions may be experienced, especially in congested city areas.
(2) The picture signal is comprised of a very wide band or range of frequencies, all of which must be received with good efficiency.
(3) It must be continually remembered that the discern- ment for the eye is much more critical than that of the ear.
Transmission Line RCA Victor has made available two types of exterior trans-
mission lines. One is a special low loss weather -proofed line having the correct surge impedance to match the RCA Victor Television antennas and the RCA Victor Television receivers. It is carried as Stock No. 9882 in 1,000,foot rolls. The second type is a standard weather -proofed line, also having the correct surge impedance for proper antenna and receiver matching. It is carried as Stock No. 12430 in 90 -foot rolls, Stock No. 12429 in 45 -foot rolls and is available in 1,000 -foot spools as Stock No. 9881. Use of improper lines may result in excessive loss or may lead to line reflections, resulting in multiple images or "ghosts," thus marring the reception.
MODELS TRK-90,TRK-120
For transmission line runs up to 200 feet, and where the signal strength on the antenna is relatively high, the Stock No. 12430, or Stock No. 12429 transmission line may be used. For all other applications the Stock No. 9882 trans- mission line is recommended. In some areas of very high. signal intensity, a lead coverer
transmission line may be advantageous.
Five -Television -Channel, Receiver Kinescope Installation (TRK-90).
1. Remove back cover of cabinet. 2. Remove the two screws which secure the wooden block,
on which the yoke is mounted, to the upper shelf, and drop this block and yoke away from the shelf.
3. Loosen the thumb screw in the center of the slotted block of wood on the top shelf, pull this block of wood to- wards the rear of the cabinet and turn it so that the "V" slot on the front end of the block is to your right.
4. Wearing gloves and goggles, carefully slide the Kine- scope on the "V" in the block, and turn both the block and the Kinescope so that the Kinescope faces the viewing win- dow. Sl?de the Kinescope up to the mask in the window and fasten loosely in place by sliding the "V" block up to the bottom of the Kinescope face, and fastening it with the thumb screw.
5. Place the yoke änd the wooden block on which it is mounted, on the Kinescope neck, rotate the block 90° from its original mounting position in order to have it clear the top of the cabinet and slide it into position on the Kinescope neck. DO NOT FORCE YOKE. In some cases where the yoke lead is too short it may be necessary to loosen the "V" block and swing the Kinescope neck to the left in order to be able to place the yoke on the Kinescope neck without forcing.
6. Fit the upper part of the wooden yoke mounting block into the slot on the underside of the cabinet top and fasten the lower end of the block securely by means of the two screws. The Kinescope should be mounted loosely in ,place, so that the yoke is not forced on the Kinescope neck at any time.
7. Loosen the wing nuts on the yoke mounting bracket, and move the yoke forward on the neck of the Kinescope so that it pushes the Kinescope against the mask. Tighten the wing nuts to hold the Kinescope and yoke securely in this position. 8. It may be necessary to rotate the Kinescope, within the limits allowed by the high voltage second anode lead, with re- spect to the mask in order to obtain proper masking of the
edges on the Kinescope screen. Before rotating the Kine- scope, the screws holding the yoke mounting block should be loosened, so that the Kinescope neck will not be forced. 9. Move the "V" block forward so that it holds the bot- tom of the Kinescope in place. Tighten the thumb screw. 10. Place the second anode lead on the second anode cap at the side of the Kinescope. 11. After the receiver is operating, and if the picture is not squared with the mask, .using a screw driver loosen the clamping screws on the band around the yoke and rotate the yoke until the picture is squared with the mask, then tighten these clamping screws securely.
CAUTION: When removing the back cover of the cabi- net, after the screws have been removed do not allow the cover to slide down on the neck of the Kinescope, or the neck of the Kinescope may be snapped off. Kinescope Installation (TRK-120).-Refer to figure 4.
1. Remove back cabinet cover. 2. Remove the top safety glass cover by removing the three wing nuts "E" at the two front corners and right rear corner of tue cover and loosening the wing nut "E" at the left rear corner of the cover. 3. Lift the cover straight upwards, taking care not to scratch the cabinet finish with the protruding screws or the cover itself.
4. Loosen the two wing nuts "F" on the yoke holding frame, and allow the yoke to drop down as far as possible.
5. Using gloves and goggles, open the Kinescope shipping carton and remove the top cover on the Kinescope.

MODELS TRK-90,TRK-120 RCA MFG. CO., INC. 6. Remove the Kinescope from the shipping carton (do
not remove the close fitting cardboard shield from the Kine- scope), and insert the Kinescope into the cabinet, guiding the neck of the Kinescope into the yoke. Do not force the neck of the Kinescope into the yoke, or the tube may break. Let the Kinescope down slowly so that it finally rests on the yoke.
7. Rotate the Kinescope and cardboard container (but not the yoke), so that the second anode cap at the side of the tube is towards the front of the cabinet.
8. Place the white rubber mask on the face of the Kine- scope, with the ribs on the mask facing upwards toward the mirror. Line up the mask so that it masks the edges on the Kinescope face. Then, if necessary, lift the Kinescope and rotate it so the mask is approximately squared up with the cover opening. The second anode cap should be kept towards the froht of the cabinet.
9. Replace the safety glass cover and wing nuts. Tighten wing nuts to hold the cover securely.
10. Loosen the wing nuts "F" on the yoke mounting bracket and push the two metal brackets, on which the bot- tom of the yoke rests, upward, until the rubber mask rests against the top cover. If the mask and the cover opening do not line up, rotate the cone -shaped Kinescope shield until they do. Tighten the wing nuts to hold the yoke and tube in this position. In some cases it may be necessary to loosen the four screws holding the yoke support to the wooden frame and shift the yoke support to make the mask and Kinescope line up symmetrically with the cover opening.
11. Place the second anode lead on the second anode cap at the side of the Kinescope.
12. After the receiver is operating, and if the picture is not squared up with the cover opening, the two screws "H" on the band around the yoke should be loosened, and the yoke rotated to square up the picture, then these screws should be tightened with a screw driver.
Focusing Control.-This is a screw driver adjustment located on the right side of the cabinet near the base.
Adjustments.-There are a series of screw driver slot ad justments at the rear of the TRK-120 (at the side of the TRK-90), used to obtain the proper picture size, centering, and vertical distribution. These adjustments are explained fully in the receiver operating instructions
Video Chassis KC -4F, KC -4H When it is desired to measure any voltages on this chassis,
the primary leads of the high voltage transformer T6 should be disconnected and taped together.
When any changes have to be made in the Video chassis, tilt lead and part locations should be replaced as closely as possible to the original positions.
Because of the special equipment and procedure necessary for the proper alignment of these receivers, the alignment will be covered in a supplementary booklet.
Refer to the booklet: Practical Television by RCA, for de- tailed explanations of circuit operation in a Television re- ceiver. Service Hints:
1. Poor Horizontal Distribution of the picture elements may be due to a 6L6 tube. RCA -6L6 tubes of known recent manufacture are the only tubes recommended for the Hori- zontal sweep output circuit. By careful scrutiny, these tubes can be identified by the three "rings" or sections welded to-
gether at the base ring of the tube, as shown in Figure 6. If any other 6L6 tube is used in this position it will break down in a vèry short time.
2. If the picture "tears out" when the receiver is jarred it may be due to microphonic 6AB7, 6AC7 or 6J5 tubes.
3. The 6J5 oscillator tube should be removed without rocking it in its socket to loosen it, as the rocking motion may cause the 80.5 mmf capacitor to break off.
4. The coils in oscillator circuit should not be touched or moved or the alignment of the receiver will be disturbed.
5. The insulator on the filter capacitors may become dirty and break down to short out the high voltage.
6. The Video coupling capacitors C50, 53, 59 should be kept clear of chassis.
7. A gassy 2V3 -G tube may cause resistor R-137 to burn. Replace 2V3 -G tube, and resistor, if necessary.
8. Changing the position of the oscillator shield plate will disturb the alignment.

6. Resistor R-165 is added. 7. Inductance L-50 is 100 ohms in this model. 8. An RCA -5T4 replaces the RCA -5U4 -G.
In addition Kinescope shielding is provided as follows: 1. A metallic conical section is installed in the cabinet to
shield the Kinescope bulb. 2. A double metallic cylindrical section is installed with the
deflecting yoke mounting assembly to shield the deflecting yoke proper. The accompanying illustration shows its assem- bly.
CAUTION: The conical shield is of the proper size to permit installing the 1803P4 Kinescope with its protective cardboard sleeve. The latter should never be removed.
To prevent Kinescope breakage, when installing a Kine- scope, the deflecting yoke and shield assembly must be in place. To- prevent breakage of Kinescope when removing the deflecting yoke and shield assembly the Kinescope must be removed first, Replacing or orienting deflecting yoke:
1. Remove Kinescope. 2. Loosen yoke support bracket wing nuts and remove
complete yoke and shield assembly. 3. Remove outer shield. Loosen yoke clamp screws to
permit removal or orientation of yoke. If it is necessary to orient yoke, pull yoke out so it extends about one inch. Tighten screws just enough to hold yoke but not too tight as it may be necessary to turn it in this extended position. Replace the inner shield and yoke in the yoke mounting brackets.
4. Replace Kinescope and protective glass cover. 5. Move the inner shield and yoke assembly vertically
until yoke is gently touching Kinescope bulb. Tighten yoke bracket wing nuts.

Precautionary Lead Dress
All A -C leads should be twisted together and dressed awa`.y from parts in chassis to prevent hum pickup.
Keep pilot light leads away from 6R7 grid.
Yellow, green, .and black leads from fidelity switch to 1st i -f transformer must be twisted together and dressed away from chassis. The same applies to the 2nd i -f transformer leads.
Victrola Attachment A jack (X-16) is located near the antenna terminal board
for convenience in plugging in a Victrola Attachment. The cable from the Victrola Attachment should be terminated in a Stock No. 31048 plug to fit the jack.
50-60 Cycle Power Supply 6. Rotate yoke carefully with one hand to orient raster or
picture. 7. Remove Kinescope. 8. Remove carefully (so as not to disturb yoke adjustment)
the inner shield and yoke assembly. Place the latter on a flat surface with the extended yoke end flush to surface. Press inner shield gently down until yoke edge is flush with inner shield edge. Tighten yoke clamp screws evenly by first pull- ing one up and then the other.
9. Assemble outer shield to inner shield and yoke assem- bly so bottoms of shields are flush.
10. Replace complete shield and yoke assembly in the yoke support bracket.
11. Replace Kinescope and tighten protective glass cover. 12. Push gently complete assembly up flush against the
Kinescope bulb. Tighten wing nuts.
IMPORTANT: 1. The hole in the conical metallic shield must line up with the hole in the protective sleeve to permit connection of the second anode cable.
2. Do not jar or drop the shields and keep away from the loudspeaker field coil to prevent magnetization.

Alignment Procedure (RADIO CHASSIS)
At Right-Tube and Trimmer Locations
Cathode -Ray Alignment is the preferable method. Connections for the oscillograph are shown in the chassis drawing.
Output Meter Alignment. - If this method is
used, connect the meter across the voice coil, and turn the receiver volume control to maximum.
Test -Oscillator. - For all alignment operations, connect the low side of the test -oscillator to the re- ceiver chassis, and keep the output as low as pos- sible to avoid a -v -c action.
Calibration Scale on Indicator -Drive -Cord Drum.-The tuning dial.is fastened in the cabinet and cannot be used for reference during alignment, therefore a calibration scale is at-
tached to the rear of the indicator -drive -cord drum which is
mounted on the front shaft of the gang condenser. The set- ting of the gang condenser is read on this scale, which is
calibrated in degrees. The correct setting of the gang in de- grees, for each alignment frequency, is given in the align- ment table.
As the first step in r -f alignment, check the position of the drum. The "0" mark on the drum scale must be vertical, and directly over the center of the gang -condenser shaft when the plates are fully meshed. The drum is held to the shaft by means of two set screws, which must be tightened securely when the drum is in the correct position.

To determine the corresponding frequency for any setting of the calibration scales, refer to the accompanying drawing which shows the dial with 0.180° calibration scales drawn at top and bottom.
Pointer for Calibration Scale.-Improvise a pointer for the calibration scale by fastening a piece of wire to the gang - condenser frame, and bend the wire so that it points to the "0" mark on the calibration scale when the plates are fully meshed.
Dial -Indicator Adjustment.-After fastening the chassis in the cabinet, attach the dial indicator to the drive cable with indicator approximately 1/16 -inch above end dots at low - frequency ends of bands with gang condenser fully meshed. See that pointer does not rub background screen or dial face. The indicator has a spring clip for attachment to the cable.

Electric Tuning Mechanism When a station button is pushed in, it completes the 24 -
volt circuit through the corresponding station -setting contact and one-half of the brass selector disc, which is connected to one side of the motor field coil. This energizes the motor, and the rotor is pulled forward,'engaging with the gear train that drives the tuning condenser and selector disc. The con- denser and disc rotate until the insulation line comes under the particular station -setting contact, and the motor circuit is broken.
When the electric tuning mechanism is in action, the motor -supply voltage is fed into a diode rectifier circuit which applies a high bias to the first -audio amplifier. This prevents audio amplification and makes the set quiet or "mute" while the mechanism is operating.

Adjustments for With power turned off, disconnect the antenna transmission
line' and ground connection, turn fidelity control to radio (3rd radio position -6th position from full counter -clock- wise). Remove the back from the cabinet and reconnect the antenna transmission line and ground connection. The two interlock switches on the side panels should not be touched and care should be taken not to press on them when making the push-button set-up. Then turn on power, set range -selector to "A," allow a few moments warm-up period and proceed as follows: 1. Make a list of the desired nine stations, arranged in order
from low to high frequencies. 2. Turn on power -volume control, turn range selector to
"A" band, and allow a few minutes for warming up. 3. Press down the "dial -tuning" (right-hand) button.

The brass selector disc is fastened to the rear shaft of the tuning condenser by means of two set -screws. When the condenser is at maximum (plates fully meshed) the insula- tion line should be horizontal, with the operating -end at the left (viewed from rear). The brass is beveled at this end.
The selector disc should be set so that the contact -tip plungers in the station -setting contacts project not more than 1/16 -in. from the body of the contacts.
LUBRICATION Motor bearings and gear bearings; use light machine oil. Gear faces; use "Pure Oil No. 611" or petroleum jelly. Dial -indicator pulleys and rails; use "Castordag" or petro-
leum jelly. Selector disc; apply thin film of petroleum jelly.

PAGE 13-62 RCA MODEL R-91 Phono.
RCA MFG. CO., INC.
General Description and Service Data The model R-91 Electric Victrola consists of a crystal pickup,
a four tube audio amplifier, a five -inch dust -proof dynamic speaker, and a motor turntable mechanism all combined in a hinged -top, table type walnut veneer cabinet. Any record, up to and including the 12 -inch size, may be played on this instrument.
The crystal pickup unit is securely sealed in a metal casing, against extreme changes of climate. If failure occurs due to a defective crystal unit, no attempt should be made to repair it, but a new replacement crystal unit should be installed.
Phonograph Motor The synchronous motor used in this instrument is designed to be
simple and foolproof. The parts that may require attention are plainly shown in figure 2. The motor' is started by turning "on" the power switch and giving the turntable a clockwise spin with the hand. Smooth starting and running will be insured by keeping the bearings well cleaned and oiled.
Hum and Vibration.-A small amount of hum when starting, decreasing to a negligible amount when running, is normal. If ex- cessive vibration occurs it may be due to:
1. Insufficient lubrication, or any failure that will cause binding. 2. Leather washer not oiled. (Check to make certain that the
leather washer is above the steel washer.) 3. Motor not properly supported from motor board. 4. Burrs on poles of rotor or stator. Remove with fine emery
cloth. 5. Stator should be free to rotate between limits of damping
assembly. Removing Rotor.-The rotor and turntable assembly simply rests
on the ball bearing at bottom of vertical bearing. Remove by lifting upward.
Rotor Adjustment.-Remove motor from cabinet. Loosen the three screws that hold the rotor to the turntable, insert three 16 -mil shims at equal distances around the gap between the rotor and stator, and then carefully tighten the three screws. The top of rotor must be flush with top of stator; add additional steel washers beneath the stator if necessary.
Pilot Lamp.-To replace pilot lamp, remove the screws from the small raised block at the front of the motor board, and remove the wooden block. The pilot lamp compartment is then accessible.

MODELS R-93B,R-93C RCA MFG. CO., INC. Phono
General Description These instruments employ a crystal pickup unit which depends upon torsional vibration to provide the necessary output
voltage. The crystal unit is contained in a metal case, securely sealed against extremes of climate. An offset mounting for the pickup head gives an ideal tracking angle between the needle and record grooves.
The motor Is a manual starting, synchronous type, designed to operate with good regularity of speed at the standard 78.26 r.p.m. Mechanically, the motor consists of a laminated stator having a large number of salient poles; a laminated rotor with a corresponding number of poles, which is affixed to the turntable; and two field coils, installed on the stator to furnish the energizing magnetic flux. The rotor, stator, and their bearing assembly are mechanically isolated from the turn- table, motor mounting, and cabinet by adequate flexible couplings and supports.
A volume control unit is associated with the record player, and its output is terminated in a twisted -pair cord with a pin -plug connector.
The two models are electrically and mechanically similar; they differ in that Model R -93B has a molded plastic cabinet, whereas Model R -93C has a veneer wood cabinet.

CONNECTING RECORD PLAYER TO RADIO RE- CEIVER-In connecting this player to the radio, care must be exercised to connect it at a point where sufficient gain is between it and the speaker to give normal output. Usually two or more stages of audio amplification are required. The radio part must be thoroughly disconnected or "killed" when playing records, else the radio signals will be heard with the record's music. Attention should be given to the possibility of introducing hum and feedback voltage into the

radio when connecting the player. A radio -phonograph switch, Stock No. 9824 is recommended for a switching system. Its connections are shown in Figure 1. With it, radio or phonograph may be selected by simply turning the switch.

Figure 3-Motor Coil Assembly and Connections
When the radio is equipped with a phonograph terminal board, the player is easily connected. One should follow the instructions pertaining to that particular radio. In general, the player's output should be applied to the grid circuit of the first audio tube in the same manner as the second detector is connected. Use a switching arrangement that grounds the radio as it connects the phonograph.
When using the radio phonograph switch Stock No. 9824 on radios using a 6B'7 or some similar tube for second detector, the yellow and green leads are connected in series with the grid cap connections of this tube. The green lead is connected to the grid cap.
RECORD PLAYER SWITCH JUMPERS-Some record player switches do not have jumpers J1 and J2 attached. When the switch is so connected and turned to phonograph position, the voltage developed by the pickup is fed into the radio receiver through the green wire and shield, and at the same time the yellow wire is connected to shield. The jumpers J1 and J2 permit the yellow lead to kill radio by connection to shield. The jumpers should be removed where the yellow lead connects in such a position as to shord bias batteries, etc. Check the switch to be used for the method chosen and use the jumpers accordingly.

Motor Data Smooth starting and running will be insured by keeping the
bearings well cleaned and oiled. Hum and Vibration-A small amount of hum when starting,
decreasing to a negligible amount when running, is normal. If excessive vibration occurs, it may be due to: 1. Insufficient lubrication, or any failure that will cause binding. 2. Leather washer not oiled. (Check to make sure that the leather
and steel washers are arranged in proper sequence, as shown in the drawings.)
3. Motor not properly fastened in cabinet. 4. Burrs on poles of motor or stator. 5. Slight eccentricity of rotor or spindle. 6. Loose laminations of the stator. 7. Improper horizontal alignment of the rotor and stator (per-
taining only to the type motor shown in Figure 1). Correct

To use the calipers, lift out the turntable and rotor, slide the caliper onto the rotor shaft, and adjust the calipers to fit the internal radius of the rotor. Rotate the calipers and check for run out, or widening of the radius. Tap the edge of the rotor to move it in the desired direction. Recheck and tap as necessary until rotation of
the calipers indicates accurate centering.
horizontal alignment is as shown in the motor assembly drawing. The position of the stator is raised or lowered by adding or removing washers below the leather washer. In the type motor shown in Figure 2, no adjustment is necessary because correct horizontal alignment is provided by the design of the motor.
The damper spring must fit without binding or chattering, in the slot in the stator. The stator must be free to deflect in either direction between the limits of the damper spring. Any binding in the washers or stator bearing which prevents the movement of the stator may cause speed variations in the motor. The damper spring must exert equal force in restoring the stator to its mid -position when the stator is deflected manually in either direction.
Tone Compensation Because of the widely varying frequency characteristics of various
types of audio amplifiers with which the Player may be used, it may be desirable in some cases to make refinements in the pickup circuit of the Player to compensate for the characteristics of the amplifier. The following circuits show means of making such refinements.
In Figure 3, R1 controls the low -frequency response; larger values of R1 give increased lows: For maximum low -frequency re- sponse, remove R1. R2 controls pickup output, smaller values of R2 giving increased output. Cl controls high -frequency response; to increase highs, increase Cl.
C1 -82MME
CRYSTAL PICKUP
Where a decrease in high -frequency response may be desired (for example, as an aid in reducing "needle scratch" on worn records), the circuit in Figure 4 is applicable. In this circuit, C2 acts as loading on the pickup and is also a controlling factor on the high - frequency response. Smaller values of C2 give more pickup output and also more highs. R3 gives a sharper high -frequency reduction; increasing R3 decreases highs.
The suggested values shown in Figures 3 and 4 should serve as a basis from which slight alterations may be made to suit individual cases.

General Description The RCA Victor Record Player Model R -94B consists of a self-
starting motor turntable mechanism, a crystal pickup, an aurally com- pensated volume control, and a motor switch. This record player can be adapted to play records through the audio amplifier -loudspeaker system of practically every type of radio receiver. The cabinet is of walnut veneer, and has a hinged lid, which locks in the "open" posi- tion -but should be closed while records are being played. Any record up to and including the 12 -inch diameter size may be played on this instrument. An automatic switch turns the motor "off" when the end of a record has been reached.
Service Data The crystal pickup unit is thoroughly sealed in a metal casing,
against extreme changes of climate. The offset mounting of the crystal unit in the pickup arm insures ideal tracking between needle and record grooves. If failure occurs due to a defective crystal unit, no attempt should be made to repair the unit, but a new replacement crystal unit should be installed.
The turntable drive, is a self-starting, variable -speed, governor -type, induction motor. The motor speed adjusting screw is located under

the turntable, which must be removed for speed adjustment. The motor speed should be 78 r.p.m., and may be checked by placing a piece of paper between a record and the turntable, with the paper protruding beyond the edge of the record, and then counting the number of revolutions of the turntable per minute. The motor is designed to be simple and foolproof in operation. Occasionally, how- ever, lubrication and certain adjustments may be required. These are illustrated and explained in figure 1. In addition, an application of oil to the felt pad, which rubs against the governor disc, will insure smooth operation.
The turntable is started by pushing to the rear the motor starting lever, which appears to the right of the turntable. The adjustment on the automatic motor stopping switch should be made so that the switch will snap to the "off" position when the needle in the pickup head is 15 inches away from the center of the turntable. The lock- ing screw and details of the switch mechanism are shown in figure 2.
The volume control is of the potentiometer type, tapped to give aural compensation at low volume settings. The output lead from the volume control is a single shielded wire, terminating: in a small, male, pin plug. See figure 3. This pin plug fits into the female jack receptacle on most of the RCA Victor 1939. "90" series of radio receivers.

Connecting Record Player to Radio Receivers A table giving methods of connecting the Record Player to various
types of audio systems is shown in the following text. Also included are the model numbers of the various RCA Victor Receivers to which the particular method shown applies. The data given in the table requires that an RCA Stock No. 9824 "Radio" -"Phono" switch be used for switching from radio to phonograph, as desired. For ease in connecting the "phono" lead to the Stock No. 9824 switch, the male plug on the end of the shielded lead should be removed by unsoldering, or cutting it off.
In general, the Record Player must be used with radio receivers having at least two stages of high -gain audio amplification. The Record Player output should be connected to the grid of the first audio tube, and at the same time the output of the radio receiver portion of the chassis should be shorted or opened, to prevent radio signals being heard while the Record Player is in operation. CONNECTING RECORD PLAYER TO:
1939 RCA RADIO RECEIVERS OF "90" SERIES :
Plug male jack on end of Record Player into female receptacle on receiver chassis. Push or turn "Phono" switch to "Phono" position, and operate Record Player according to instructions.

Alignment Procedure Cathode -Ray Alignment is the preferable method. Connections for
the oscillograph are shown in the schematic diagram. Output Meter Alignment. -1f this method is used, connect the
meter across the voice coil, and turn the receiver volume control to maximum.
Test -Oscillator. - For all alignment operations, connect the low side of the test oscillator to the common negative, and keep the output as low as possible to avoid a -v -c action.
Electronic Voltmeter. -The electronic voltmeter in the Chanalyst or VoltOhmyst provides an unexcelled output indicator. It should be connected to the AVC bus, and the test -oscillator output adjusted to produce several volts of AVC.
Calibration Scale. -The glass tuning dial may be easily removed from the .cabinet 'and temporarily attached to the chassis for 'quick reference during alignment. In the event that only the chassis is
-returned for service, and the cabinet with its tuning dial is left in the customer's, home, the scale printed in this service note can be used as an accurate and convenient substitute for the regular dial. With gang in full mesh, move the dial pointer to a point 1/16 inch to left of reference mark at left hand end of the dial backing plate. Place the dial under the pointer so that the extreme left scale gradua- tion coincides with the pointer. Use scotch tape to hold the dial in place.

6. Proceed in the same manner to adjust for the remaining stations.
On the 880 to 1,800 kc push-buttón, the higher frequency sta- tions may be received with osc. core either in or out (oscillator fre- quency either 466 kc below or 455 kc above the station frequency). The adjustment with this core in its out position (oscillatorfre- quency 455 kc above the station frequency) is the correct one.
NOTE: Clockwise adjustment of cores and trimmers tunes the cir- cuits to lower frequencies.

25 m 13 14 i9m) The dial scale drawing shown is a full size reproduction. It can be used as a direct substitute for
regular dial scale in alignment procedure.
Cathode -Ray Alignment is the preferable method. Connections for the oscillograph are shown in the schematic diagram.
Output Meter Alignment.-If this method is used, connect the meter across the voice coil, and turn the receiver volume control to maximum.
Test-Oscillator.-For all alignment operations, connect the low side of the test -oscillator to the receiver chassis, and keep the output as low as possible to avoid a -v -c action.
Electronic Voltmeter.-The electronic voltmeter in the Chanalyst or VoltOhmyst provides an unexcelled output indicator. It should be connected to the AVC bus, and the test -oscillator output adjusted to produce several volts of AVC.
Calibration Scale.-The glass tuning dial may be easily removed from the cabinet and temporarily attacked to the chassis for quick reference during alignment. In the event that only the chassis is returned for service, and the cabinet with its tuning dial is left in the customer's home, the scale printed in this service note can be used as an accurate and convenient substitute for the regular dial.
Using Tuning Dial. - 1. Remove glass dial from the cabinet.
2. With gang in full mesh, move the dial pointer to a point 1/16 inch to left of reference mark at left hand end of the dial backing plate.
3. Place the glass dial under the pointer so that the extreme left scale graduation coincides with the pointer. Use scotch ape to hold the glass dial in place.
"C" Band Reception-For best reception on "C" band with an outside antenna, adjust the trimmer screw on the RF coil on the chassis. Turn screw carefully with a special screwdriver (RCA Stock No. 31081) while the receiver is tuned to a station in the 31 -meter band, and make setting for best reception. If returning to internal antenna at any time, close the link on the center terminal and adjust "C" band antenna trimmer for best reception on 31 -meter band.

Calibration for Alignment.- A calibration scale is attached to the tuning drum. The correct setting of the gang, in degrees, for each alignment frequency is given in the alignment table. Check the position of the drum, making sure that the 140 degree scale mark is directly above condenser shaft wi.en the gang is at minimum setting.
Pointer for Calibration Scale.- Improvise a pointer for the calibration scale by fastening a piece
of wire to the chassis, and bend the wire so that it points to 0 degree mark on the calibration scale when the plates are fully meshed.

Push Button Adjustment. The station push buttons connect to separate magnetite -core oscil-
lator coils and separate antenna trimmers which must be adjusted for the desired stations. Use an insulated screwdriver or alignment tool such as RCA Stock No. 31031. Allow at least five minutes warm- up period before making adjustments.
In the event that the receiver is to be used with an external an- tenna use one or two feet of wire (as an antenna) to ensure sharp peaking during the final adjustment procedure. For loop operation, the link should be strapped across terminals on back of set. In either case the procedure is as follows:
1. Make a list of the desired stations, arranged in order from low to high frequencies.
2. Turn the range selector to "A" band, and manually tune in the first station on the list.
3. Turn range selector to "PB" position, push in station button No. 1 (extreme left). Then adjust the No. 1 oscillator core to receive the station.
4. After oscillator core is set correctly, adjust No. 1 antenna trim- mer for maximum output.

Clockwise adjustment of cores and trimmers tunes the circuits to lower frequencies.
5. Adjust for each of the remaining stations in the same manner. 6. Make a final careful adjustment of the oscillator cores and an-
tenna tritnmers. On the 880 to 1.600 kc push-button, the higher frequency stations
may be received with No. 1 oscillator core either in or out (oscillator frequency either 455 kc below or 455 kc above the station frequency). The adjustment with this core in its out position (oscillator frequency 455 kc above the station frequency) is the correct one.

Output Meter Alignment.-Connect the meter across the voice coil. and turn the receiver volume control to maximum.
Test-Oscillator.-Connect the low side of the test -oscillator to the receiver chassis, through a .01 mfd. capacitor, and keep the output as low as possible.
Phonograph Motor Service Data:- The phonograph motor is of the self starting synchronous type and
operates the turntable through friction drive between the motor drive spindle and the rubber tired idler on the rim of the turntable.
The motor should be lubricated once or twice a year by placing a few drops of S. A. E. 20 (or equivalent) on the turntable spindle and saturating the oil retaining felt pads on the motor shaft with S. A. E. 10 oil. Caution-The motor drive spindle and the rubber tire on the idler must be kept clean and entirely free from oil and grease at all times.
Power Supply.-Although this model employs an ac -dc chassis, it is not suitable for use on d.c., as this would damage the motor.

The MI -4836, 48i8 equipments are designed for regular Public Address use, while the MI -4817 is designed for Sound Truck (6 volt) operation. Standard, 78 rpm,
records may be played on the MI -48i6 and MI -4818. The
MI -4817 has provision for changing the speed of the
turntable to enable both 78 rpm and 33-i/3 rpm re-
cords to be played. A low -impedance (125 ohm) mag-
netic pickup is used, designed primarily to use
chromium (RCA orange or green shank) needles. The
output of the pickup is fed through o volume control
into a standard phone plug, or, for permanent con-
nection, the plug may be removed, and the wires
soldered directly to the amplifier input. CAUTION:

General Description The MI -4829 and MI -4829A are portable turntables for
playing of laterally cut records up to 16 inches in diameter, at either 78 or 33/ r.p.m. They use a governor type motor which is adjustable over a wide range of speed, and operate on 105/125 volts 50 to 60 cycles. An output jack and shielded cable is provided for connection to an external amplifier. The MI -4829 is equipped with a high impedance crystal pickup. The MI -4829A uses a low impedance mag- netic pickup for connection to 250 -ohm amplifier inputs. Both have an integral volume control for controlling the input level to an external amplifier.

Operation 1. Plug pickup cable into motor board receptacle. 2. Connect shield lead to ground on the proper amplifier,
and red lead to "high" side of amplifier input. (To sleeve and tip of telephone plug respectively,'if used.)
3. Set speed selecting mechanism to the proper position, corresponding to type of record used.
4. If 16 -inch records are to be played, first place special 16 -inch flocked disc on the turntable.
5. When carrying records in cover, place 16 -inch flocked disc between records and clamping disc to prevent records from warping.
Speed regulation:-Check speed in the 78 r.p.m. position by placing a piece of paper between a record and the turn- table with the paper protruding beyond the edge of the rec- ord, and counting the number of revolutions of the turntable per minute while playing the record.
Should it be necessary to reset the pointer such that 78
r.p.m. can be obtained near the center of the "F -S" scale, remove motorboard from cabinet and take off the turntable first removing the "C" washer from the turntable spindle. Set pointer off scale approximately % inch beyond the "F" mark. Loosen slightly the pointer arm screw and nut that clamps it to the slotted cam shaft. Then with a screw driver, adjust the cam such that the minimum radius of the cam is against the governor adjustment ball bearing. Tighten the pointer arm screw and nut in this position.
No separate adjustment is_ provided for 33/ r.p.m. since
with the speed properly adjusted for 78 r.p.m. records, the
speed for long playing records will be. 33/ r.p.m. when
the control lever is set at 33/.

MODEL MI -12754 RCA MFG. -CO., INC.
General Description The MI.12754 Sound Truck Equipment consists of a com-
bined 25 watt amplifier -turntable assembly, two permanent magnet speakers and an MI.6228A microphone. This equip- ment may be used on a 6 -volt D -C supply, or 110-vòlt A -C supply by merely changing the power supply cord and as- sociated plugs. The A -C and D -C cords are supplied with the equipment. This equipment may be used for permanent or mobile installations.
Input.-There are two input channels with separate volume controls. Each channel has provision for high impedance phonograph or microphone input, and both channels may be used simultaneously.
Channel No. 1 has provision for either microphone or phonograph input. Microphone input to this channel is through the receptacle at the rear of cabinet marked "MIC. 1." Phono. input is either through the jack at the rear of the cabinet marked "PHONO." or through the receptacle marked "MIC. 1." Proper connections to the input plug can be determined from the schematic diagram. Both micro- phone and phono. pickup may be used simultaneously on this channel if provision is made for controlling the volume of the pickup separately.
The phono. pickup located on the cabinet is permanently connected to channel No. 2. If it is desired to use channel No. 2 for a microphone, then the microphone should be connected to the receptacle marked "MIC. 2," located at the rear of the cabinet. Both microphone and phono. cannot be used simultaneously, due to a possible difference in sound level, because no provision is made for controlling the volume of either one separately.
If additional phono. pickup is desired, for a -c operation the RCA R-93 or MI.4816 portable turntable phono. pickup may be used. For 6 -volt d -c operation, the MI.4817 portable turntable may be used. For additional microphones, an RCA MI.4036 or an additional MI.6228A microphone may be used.
Due to the fact that the signal level of each channel is controlled electrically and not in the signal circuit, remote control is possible at any point removed from the amplifier at a distance not exceeding 2,000 ft. The remote control unit is available as a separate unit and is connected to the amplifier by a cable and plug which fits into a socket provided on the rear of the main amplifier case. The remote mixing controls available are: MI -4123 which comes without cord or plug for use where the amplifier and wiring are permanently installed. MI -4123A which is identical to the MI.4123 except that a 30 ft. five conductor cable with plug attached, is in- cluded in this assembly. A 50 ft. extension cable with male and female plugs is stocked as MI -4.685. MI -45, five con- ductor cable, is recommended for connecting the remote control to the amplifier. No. 18 R.C. wire may be used.
Two output receptacles are provided at the rear of the amplifier case. Output impedances of 4, 71/2, 15, 60 and 250 ohms are available.

Microphones Two recommended types of microphones are available for
use with the MI.12754 amplifier. For orchestrations, and where close talking is not necessary, the RCA type MI -4036 junior velocity microphone will give excellent results. The MI.4036 will operate into inputs of either 50, 250 or 15,000 ohms impedance, and therefore, by making the proper connections to the microphone transformer, the microphone can be used for the High Impedance input. For average announcing purposes the MI -6228A Aerodynamic Microphone is excel- lent. The output impedance of this microphone is 40,000

ohms. Thus it may be directly plugged into the microphone input jack on the amplifier.
Stands for the MI.4036 microphone are available as follows:
