Very useful Service Manual! With it I was able to identify the damaged pots in my old amplifier, purchase the adequate replacements and make myself the repair.
I have again my old amplifier, still a very good one that I will keep for as many years as I can!
Thanks to Owner Manuals!

I'm quite impressed. I had to wait 24 hours for my manual (quite a rare one) but I got it and the quality was good. Also, from trawling the web, these prices are by far the best.

(4) Alignment for FM IF and FM Tracking
Step Item Required Instrument & Connection Instrument 1 IF Genescope Input IC201 Note 3 2 (1) (2) (3) FM FM signal Generator 400 Hz, 22.5 kHz Dev Note 6 P1 TP1 90.2 MHz 106.1 MHz Output TP1 Genescope or SG Freq. 10.7 MHz Receiving Freq. (Set) High End (or 106.1 MHz)Freq. 90.2 MHz 106.1 MHz L201 CT201 T201 Max. Note 4 Max. Adjust Reading
Repeat steps (1) & (2)
Note: 1. Feed in a week signal from the Genescope. Adjust T202 for max. gain and the waveform of Fig. 1. 2. Connect AM signal generator to loop antenna, bring near to ferrite antenna. 3. Input signal methode as follows.
4. Feed in a week signal to IC201 (Note 3) from the genescope. Use the T201 core to from the Scurve shown in the Fig. 2. Adjust the symmetry of A and B about point C for linearity. 5. SW1, SW2 dummy antenna is shown in Fig. 3. 6. FM dummy antenna is shown in Fig. 4.
R1=Rg=SG's output impedance (75 �), R2=75 - Rg/2
(5) Alignment for Clock Time Accuracy
Band FM Adjustment CT301 Procedure 1) Tune FM to 108 MHz 2) Connect a Freq. Counter to J308 3) Adjust CT301 to reach the frequency 118.7 MHz ±1.5 kHz To J308 To Counter Connection
