Penfold VCO




R.A. Penfold's Electronic Synthesiser Construction includes a number of PCB layouts for analogue synthesizer modules. Here's a dual VCO card, using one of his designs. The second VCO card is yet to be added. The controls range and square/triangle. The two jack sockets are CV and audio out. Tested the first VCO circuit today, and it works fine.
