The River Synths Nucleus DIY VCF is a dual voltage controlled amplifier with a discrete OTA core
This is a full kit set in the Eurorack format. Most components have been pre-soldered as SMT parts!
From River Synths:
After overlooking VCAs for many years, I began to appreciate the huge range of functions they can serve up. They’re really everywhere, in simple loudness contouring circuits, tremolo effects, tone controls, filters, overdrives, mixers, amplitude modulators, panners, cross-faders, and CV performance controllers. I also learned that VCAs put their subtle signature on the overall sound of an instrument.
The VCAs in the Crux are built around newly designed operational transconductance amplifier (OTA) circuits, built from discrete transistors. If you need a super-accurate VCA, this is not for you. However, if you appreciate the warm and lively nature of discrete electronics, the Crux will serve you well.
