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.
SECTION 3 ELECTRICAL ADJUSTMENT
BIAS ADJUSTMENT
Adjustment Procedure: 1. Rotate fully the bias adjusting semi-fixed resistors (RV301 (LCH), RV351 (R-CH)) to the minimum position (counterclockwise). 2. Connect a digital voltmeter to the CN406 (L-CH) and CN407 (R-CH).

3. Set the slidack to 0 V AC, and press the POWER button (ON) on the set. 4. Raise gradually the slidack voltage up to the rated voltage (230 V AC). 5. At this time, confirm that the speaker relay is turned on (it will click). 6. Adjust the RV301 (L-CH) and RV351 (R-CH) so that a reading of digital voltmeter is from 10 mV to 20 mV. 7. Return the slidack to 0 V AC, and press the POWER button (OFF) on the set.
