Circuit Overview:
     A simple single vco subtractive analog synth similar in many ways to other CS series.

Service Tips:
     Typical problems in CS series are power supply over voltages which blow tantalum capacitors and they short, or the caps just fail over the years. During this various chips may be taken out. I've seen LFO chip, VCA's and dac comparator fail so they might be most susceptable.

Parts:
I believe I should have any electronic part or keys for these save exact transformer, etc. Ask if you have need.
