Very clear copy of the philips service manual. Fast delivery. Thank you very much

Excellent manual, detailed, very useful! Exactly what I needed, I'd recommend it to all who need it. Although images are scanned easily readable and explicit. A valuable tool product at a price more than modest, take it with confidence and you will not regret it!

<TAPE PLAYER> 1. Azimuth Adjustment Settings : � Test tape : � Test point : TTA-320 PHONES JACK (J102) 2) Set the tape speed (using speed adjustment SFR). 3) Restrict the motor rotation by hand (or turn PAUSE ON). 4) Remove your hand and listen to the beginning of the tape-run. 5) When the rise of tape running is smooth, no more adjustment is necessary. If wow continues for 1 to 2 seconds at the rise time, Reduce the combined resistance according to procedure 6 and check that the tape starts running smooth. 6) Solder the resistor pattern according to the table below. 2. Tape Speed Adjustment Settings : � Test tape : � Test point : TTA-100 PHONES JACK

� Adjustment location : Azimuth adjustment screw � VOLUME : � GEQ : MAX NORMAL
Method : Play back the 8kHz signal of the test tape and adjust so that the output becomes maximum.
(J102) � Adjustment location : SFR101 � GEQ : NORMAL Method : Play back the test tape and adjust for 3015Hz ± 10Hz. 3. Motor Load Adjustment Perform the STOP to PLAY after the motor is replaced. When the tape starts running smooth, this adjustment is not necessary. this adjustment following the procedure below. 1) Solder only medium resistor pattern (B) of the MOTOR AND GOVERNOR MATCHING ADJ. Resistor group.
7) Finally recheck the tape speed. Caution : Cool the patterns down to normal temperature after soldering. If the pattern remains heated, the governor circuit does not operate normally.
