exactly as they say. Within 24 hours the link to the pages and offcourse it was the right service manual. Super and thanks
 ;
The manual was exact the thing that was promised. My old car stereo is working again thanks to the information supplied.
;
I PURHASED THIS PRODUCT BECAUSE I WAS HAVING PROBLEMS WITH MY CDR20 HARMAN KARDON RECORDER. WHICH I PURCHASED NEW 12 YEARS AGO. AFTER REVIEWING THE MANUAL, I WAS ABLE TO ADJUST THE TENSIONER IN THE SYSTEM. WORKS LIKE A CHAMP!.
SAVED ME AT LEAST 100.00 WHICH WAS WHAT A SERVICE REPAIR STATION WANTED. GREAT MANUAL EASY TO READ. SPECIALLY AFTER I PRINTED THE PAGES WHICH DEALT WITH MY RECORDER. THANKS A LOT!!!!!!!!
;
You can fully trust on this one!
All the schematics are very crear an in one piece per page
;
I have never bought a service manual which is as competely readable as this althogh it was a scanned pdf. Thank you for this succesful manual also cheaper than other sites.

< DECK SECTION > 10. 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. 11. 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. 12. 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. 13. 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. 14. 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. 15. 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 > 16. 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 atthe test point is 153.84Hz ± 0.15Hz.
Method : Set to AM 1602kHz and check that the test point is 2052kHz ± 45Hz. 2. MW VT Check Settings : � Test point : TP1 (VT) Method : Set to MW 1602kHz, 531kHz and check that the test point is less than 8.0V (1602kHz) and more than 0.6V (531kHz). 3. LW VT Adjustment Settings : � Test point : TP1 (VT) � Adjustment location: L942 Method : Set to LW 144kHz and adjust L942 so that the test point is 1.3V ± 0.05V. Then set to LW 290kHz and check that the test point is less than 8.0V. 4. 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). 5. MW Tracking Adjustment Settings : � Test point : TP8(Lch), TP9(Rch) � Adjustment location : L951(1/3) ...................................... 999kHz Method : Set to MW 999kHz and adjust L951(1/3) so that the level at the test point becomes maximum. 6. LW Tracking Adjustment Settings : � Test point : TP8(Lch), TP9(Rch) � Adjustment location : L941, TC942 Method : Set up TC943 to center position. Set to LW 144kHz and adjust L941 so that the level at test point becomes maximum. Then set to LW 290kHz and adjust TC942 so that the level at test point becomes maximum.
