2015-09 Line out for the Yamaha CN-70

I got this for $30 or less. I have the room right now and it seemed in good nick and is. I removed an odd mixer that had been added but came without its power supply so was useless. I had been hoping to use it for a line out. (The organ is very well built for service).
That got me thinking about adding a line out. Found a circuit diagram. Found some room on the side panel. Had the parts.
Test Point 82 clearly indicated on the main board is just before the Expression peddle and the main Vol so that's about right. Drilled a hole and made a plate to hold a 6.5mm jack socket.

Mounted it, soldered it up and tried it out.




Noisy but good. I think the way to fix the noise would be to go back toward the tone banks, make a low noise amp and pick it up from there. There'd be no rhythm or auto play stuff that way though but I was toying with giving them their own outputs anyway. Maybe later.
Sounds AWESOME through last months PTOM (a spring line reverb tank reverb. must write it up). Very Marty Rev
