Circuit Overview:
     Certainly one of the more elaborate analog subtractive synths. Will review circuit when I get time.

Service Tips:


I stock remanufactured knobs for these machines! Rotating small skirted knobs 3.75 each large $5 each.

Semiconductors etc.

I have a variety of parts that might help you on these as it appears Roland used many of the same parts those years. And also there are some discrete components that I usually stock.
