very helpfull
circuit diagram and sparepart list available
 ;
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.
