Very good manual, in depth and complete. Only criticism is that some of the circuit diagrams are slightly blurry and hard to follow for long periods of time, but this is to be expected. Perfect for any maintenance required. Also contains the wiring diagrams of the control cable for constructing extensions.

1. AM IF Adjustment IFT451 ................................................................... 450 kHz 2. FM IF Adjustment CT402 .................................................................. 10.7 MHz 3. AM VT Check Settings : � Test point : TP3 (VT) Method : Set to AM 531 kHz and check that the test point is 1.2 V ± 0.3 V. Then set to AM 1602 kHz and 1check that the test point is less than 7.8 V. 4. FM VT Check Settings : � Test point : TP3 (VT) Method : Set to FM 87.5 MHz and check that the test point voltage is 3.5 V ± 0.3 V. Then set to FM 108.0 MHz and check that the test point voltage is less than 8.5 V. 5. AM Tracking Adjustment L451 ...................................................................... 630 kHz CT451 .................................................................. 1440 kHz 6. FM Tracking Adjustment CT401 .................................................................. 87.5 MHz 7. FM VCO Adjustment Settings : � Adjustment location : SFR451 Method : Connect a frequency counter to pin 11 & 12 of IC451. Adjust SFR 451 such that the frequency counter indicates 19kHz ± 100 Hz.

8. Tape Speed Adjustment Settings : � Test tape : TTA�100 � Test point : Phones Jack (J101) � Adjustment location : SFR201 � DSL : OFF Method : Play back the test tape and adjust SFR201 for 3015 Hz ± 10 Hz (FWD) and 3015 Hz ± 50 Hz (REV). Then confirm WOW is less than 0.5%. 9. Dolby Level Adjustment Settings : � Test tape : TTA�200 � Test point : TP1(LCH), TP2(RCH) � Adjustment location : A, D (LCH) B, C (RCH) � VOLUME : MIN "0" � DOLBY SW(AU) : OFF Method : Connect a coupling capacitor (10 uF / 16 V) between the test point and AC voltage meter about. Check the test point voltage for 32 mV ± 1.0 dB. If TP1,TP2 level is different from the SPEC, perform this adjustment following the procedure below: Out level 32mV + 1dB up 32mV + 2dB up 32mV + 2.7dB up TP2 (RCH) 32mV + 1dB up 32mV + 2dB up 32mV + 2.7dB up Solder place D A A, D C B B, C
