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.

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

(2) Basic construction (Initial position of the planetary gear mechanism) 1) Even after the disc has been inserted, the motor rotated and the gear train also rotated, slider (R) does not start operation yet.This is because the planetary gear mechanism is used and the carrier gear is locked by the slider mechanism. In this period, the planetary gear is in the loose condition. 2) When the sun gear is rotating and the carrier gear is locked, the planetary gear is running idle.

(3) Basic construction (Construction of the trigger slider and slider (R)) The trigger slider is assembled with slider (R) and pushed in the direction of the arrow by the force of a spring.

(4) Operation of slider (R) 1) Activating the trigger slider When the trigger arm is rotated by the pressure of the disc, the trigger arm pushes the trigger slider.

2) Rotating (engaging) the planetary gear When the trigger slider is moved, it pushes down the wall (section A) of the carrier gear. (Initial rotation of the carrier gear) This causes the planetary gear, which is attached on a pin of the carrier gear, to move according to the rotation of the carrier gear. When the planetary gear is meshed with a gear tooth (section B) of the traverse chassis, the planetary gear starts rotation. The rotation of the planetary gears causes the carrier gear to rotate.
