I found your documentation when I started repairing my Crumar Composer, thanks a lot for that, it helped me a lot. :) I have also watched some of your repair videos, those have also helped me.
I have put a lot of hours into this synth, even replacing all caps, but it sounds SO good and is very inspiring so I think it's worth it. It had a lot of problems, now there's just a few left (unable to select one of the string presets and the organ presets sometimes all light up). Those problems are to bad solder joints I think, I have found several bad solder joints and replaced ic sockets since some were bad.
I'm still a beginner with synth repair but by repairing this synth I have learned a lot, not finding a schematic has made it harder.
