Circuit Overview:
     SK series synths I believe are divide down oscillators with some analog circuitry and some digital stuff going on. Anyone have a better description? Hope to get one of these soon.

Service Tips:

While Yamaha normally does not keep parts around more than 5 years or so, I stock what I can. Some knobs in stock.
