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.
KMC-35/36
CIRCUIT DESCRIPTION
Hot Microphone Function
In the Hot microphone state, only microphones whose PTT switch is pressed can send modulation signals in the environment in which several microphones are connected to the transceiver in parallel. In the Normal microphone state, if the PTT switch on one of the microphones is pressed, modulation signals are sent from all microphones.
â� Circuit description
Hot microphone operation can be performed by cutting the jumper (JP1). If the jumper is not cut (Normal microphone state), bias voltage is always applied to the microphone element (Q3 is always ON) and if the microphone mute of the transceiver to which the KMC-35/36 is connected is released, modulation signals can be sent even when the microphone PTT switch is not pressed. If the jumper is cut (Hot microphone state), bias voltage is applied to the microphone element only when the PTT switch is pressed (Q3 turns ON only when the PTT SW is pressed), and modulation signals cannot be sent when the microphone PTT switch is not pressed.
