Circuit Overview:
Certainly one of the more elaborate analog subtractive synths. Will review circuit when I get time.
Service Tips:
Anyone?
Parts:
Knobs
I stock remanufactured knobs for these machines! Slider or rotating small 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.
