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.

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.

1) Don't place Clock chip edge. Place near PCB center and mounting hole.
Make the clock generator area more "clean"
2) Every power pins have a decoupling CAP direct connect it.
Make the shortest trace.
3) Ground pin directly connect to ground plane.
4) Make trace power ground pin short and wider than width of chip pad.
5) Don't place via between clock chip power pin and decoupling CAP.
6) Clock trace must have damping resistor and filter Capacitor near to clock chip output pin.
A
7) No other signal trace across through the clock generator area.
Including crystal, clock chip, decoupling capacitor, damping and filter.
