Impressively thorough. Even the simple operators manual helped me "fix" one of the 2 CD players in the unit. This unit reads CD's from the top so they should be installed in the magazines "upside down" from typical CD players. The CD player service manual helped me unjam a stuck carriage because somebody transported the box laying down loaded with CD's. A little lens cleaning & the player now works well! Thanks for you help at a great price! Joe

I was skeptical at first but later found the manual to be good quality for the price. It took a couple hours to receive the email with the download link, well worth the wait. Thanks.

Good manual, schematics nice and clear with good quality scanning. Woul dhave been nice to have immediate access after purchasing though.

I was very glad recieving the service manal from You. Manuals were delivered promptly and were correct as advertised. A complete and very usefull service manual with all details. Thank you!
< TUNER SECTION > 1. Clock frequency Check Settings : � Test point : TP2 Method : Set to AM 1710kHz and check that the test point is 2160kHz ± 45Hz. 2. AM VT Check Settings : � Test point : TP1 (VT) Method : Set to AM 1710kHz, 530kHz and check that the test point is less than 8.5V (1710kHz) and more than 0.6V (530kHz). 3. FM VT Check Settings : � Test point : TP1 (VT) Method : Set to FM 87.5MHz, 108.0MHz and check that the test point is more than 0.5V (87.5MHz) and less than 8.0V (108.0MHz). 4. AM Tracking Adjustment Settings : � Test point : TP8(Lch), TP9(Rch) � Adjustment location : L951(1/3) ...................................... 1000kHz Method : Set to AM 1000kHz and adjust L951(1/3) so that the level at the test point becomes maximum. 5. FM Tracking Check Settings : � Test point : TP8(Lch), TP9(Rch) Method : Set to FM 98.0MHz and check that the test point is less than 9dBµV. 6. AM IF Adjustment Settings : � Test point : TP8(Lch), TP9(Rch) � Adjustment location : L802 ............................................. 1000kHz 7. DC Balance / Mono Distortion Adjustment Settings : � Test point : TP3, TP4 (DC Balance) : TP8(Lch), TP9(Rch) (Distortion) � Adjustment location : L801 � Input level : 60dBµV Method : Set to FM 98.0MHz and adjust L801 so that the voltage between TP3 and TP4 becomes 0V ± 0.3V. Next, check that the distortion is less than 1.3%. < DECK SECTION > 8. Tape Speed Adjustment (DECK 2) Settings : � Test tape : TTA�100 � Test point : TP8(Lch), TP9(Rch) � Adjustment location : SFR1 Method : Play back the test tape and adjust SFR1 so that the frequency counter reads 3000Hz ± 5Hz and ±45Hz (REV) with respect to forward speed. 9. Head Azimuth Adjustment (DECK 1, DECK 2) Settings : � Test tape : TTA�330 � Test point : TP8(Lch), TP9(Rch) � Adjustment location : Head azimuth adjustment screw Method : Play back (FWD) the 8kHz signal of the test tape and adjust screw so that the output becomes maximum. Next, perform on REV PLAY mode.
10. PB Frequency Response Check (DECK 1, DECK 2) Settings : � Test tape : TTA�300 � Test point :TP8(Lch), TP9(Rch) Method : Play back the 315Hz and 8kHz signals of the test tape and check that the output ratio of the 8kHz signal with respect to that of the 315Hz signal is within 5dB. 11. PB Sensitivity Check (DECK 1, DECK 2) Settings : � Test tape : TTA�200 � Test point : TP8(Lch), TP9(Rch) Method : Play back the test tape and check that the output level of the test point is 140mV ± 3dB. 12. REC/PB Frequency Response Adjustment (DECK 2) Settings : � Test tape : TTA�602 � Test point : TP8(Lch), TP9(Rch) � Input signal : 1kHz / 8kHz (LINE IN) � Adjustment location : SFR451 (Lch) SFR452 (Rch) Method : Apply a 1kHz signal and REC mode. Then adjust OSC attenuator so that the output level at the TP8, TP9 becomes -20VU. Record and play back the 1kHz and 8kHz signals and adjust SFRs so that the output of the 8kHz signals becomes 0dB ± 0.5dB with respect to that of the 1kHz signal. 13. REC/PB Sensitivity Check (DECK 2) Settings : � Test tape : TTA�602 � Test point : TP8(Lch), TP9(Rch) � Input signal : 1kHz (LINE IN) Method : Apply a 1kHz signal and REC mode. Then adjust OSC attenuator so that the output level at TP8, TP9 becomes 0VU. Record and play back the 1kHz signals and check that the output is �2dB ± 3.0dB. < FRONT SECTION > 14. µ-CON OSC Adjustment Settings : � Test point : TP7 and GND � Adjustment location : L331 Method : Insert AC plug while pressing POWER and TUNER function keys. Adjust L331 so that the frequency at the test point is 153.84Hz ± 0.15Hz.
