VCF schematic

The first of the schematics. This is the production version of the Synthasystem VCF. There are some subtle differences from the other Steiner VCF clones, notably  in the feedback loop and "Q" and in the variable resistor "diode" chain. The PCB I laid out makes it possible to use discrete transistors or a match pair like a SSM2210. Nyle had a look at this one a said it looked like it incorporated the latest revisions.



  1. You're welcome. More are coming and PCBs as I get production versions checked out.
