Hi there, great that there are places like this here! I am working on a project to turn a salvaged yamaha electone b-6e and an old broken harmonix guitar amp into an guitar amp.
I have a vision, just not all the information I need to realize it. So far I have the amp unit, several boards, a pedal, a spring reverb unit, the original speaker and all the potis and switches from the organ, which I want to use for the amp. I reall like the bassy sound this combination makes.
Unfortunatly I cant find any schematics for the organ, so I guess I will have to find out what is what and how it works. Lets start with the amp.
I know the organ was 85W total, the speaker is 25w/8 ohm. It is in working condition, and cleaned. It has an american tone cab/recording socket, a line in cinch socket, one internal Output socket with 3 wires, and an internal vol input socket with 6 wires. Now I've tried everywhere, but I cant find schematics for this amp either. The board has "M-N7l", "Yamaha" and "LC0890" printed on it. The chassis is stamped with what seems to be "ND2012A"
My goal is to use the amp, the spring reverb and the speaker from the Electone, a delay from a Dr. Böhm organ, the tone control from the harmonix amp and put it all into one guitar amp chassis.
Any hints of what my first steps should be are welcome. My guess was to start with the amp and find out all I can, so I can find out where and how to integrate the effects and the tone control into the circuitry.
Im aware of the health risks, precautions will be taken. Thanks in advance for any productive advice.
