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.

Laser Current Check * Perform this check only when the laser is faulty. 1) Connect a digital multimeter across the resistor R541 (10 ohms). 2) Playback TCD-782 and check the DC voltage value of the 3) 4) digital multimeter. Check the SPEC VALUE specified on the label of pickup. Calculate the laser current (Iop) by diving the DC voltage value across R541 by the resistor value (R541 = 10 ohms). Check that the laser current (Iop) is SPEC VALUE ± 10 %.
