Very good reproduction (copy) of original manual. Didn't have a parts list, but schematic was completely labeled with parts. Complete instructions on how to adjust mechanical functions of the 8-track deck. Well worth having and at a very reasonable cost.
;
It's a full manual. All the parts are in there. I haven't found the problem yett, but I am working on it; hope I can rebuild the part myself. To make it more secure and unbreakable this time. Because the part has failed several times before and costs a lot to let it be repaired.
Thanks so much for this rich illustrated and parted manual.

I downloaded the document. The manual was complete, well scanned and everything was legible. I could zoom in see what I needed to know. There's not much more that you can ask.

It was complete service manual with all needed service informations. Thanks.

El manual esta muy detallado, los numeros de partes y los esquemas de despiece son correctísimos y muy claros, tanto para los técnicos experimentados como para los novatos.

8. Tape Speed Adjustment (DECK 2) Settings : � Test tape : TTA�100 � Test point : TP8 (Lch), TP9 (Rch) � Adjustment location : SFR1 Method : Play back (FWD) 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. 10. PB Frequency Response Check (DECK 1, DECK 2) Settings : � Test tape : TTA�330 � 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 230mV ± 3dB. 12. REC/PB Frequency Response Adjustment (DECK 2) Settings : � Test tape : TTA�602 � Test point : TP8 (Lch), TP9 (Rch) � Input signal : 1kHz / 10kHz (LINE IN) � Adjustment location : SFR351 (Lch) SFR352 (Rch) Method : Apply a 1kHz signal and REC mode. Then adjust OSC attenuator so that the output level at the TP8, TP9 becomes 0dB (16mV). Record and play back the 1kHz and 10kHz signals and adjust SFRs so that the output of the 10kHz 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 0dB (160mV). Record and play back the 1kHz signals and check that the output is 0dB ± 3.5dB.

14. MICON OSC Adjustment Settings : � Test point : TP7 (O-KSCAN) and D-GND � Adjustment location : L101 Method : Pull out AC plug, then insert AC plug again with pressing of TUNER / BAND function key and POWER key. Adjust L101 so that the frequency across the test point is 208.80Hz ± 0.21Hz or 4.78ms ~ 4.79ms.
