Circuit Overview:
Classic 2 VCO analog subtracive synth with a 40 step sequencer and arpeggiator.
Service Tips:
Aside from obviously tracing signals around curtis chips and standard aged power supply cap issues etc. I haven't heard of any other real weakness.
A lot of discrete parts in these so let me know if you need anything. A company has created a replacement for the cpu at BMH
