THAT-2180 based VCA (updated design, 4HP - FR4 panel)
Unlike some others, this module is built around the THAT2180 Blackmer cell IC - I find it easier to use, and less prone to self-destruction, than the V2164. There are a couple of different versions of the THAT2180 (A and B) but unless you're looking for insanely low levels of THD the C variant gives the best bang for the buck, so that's what I've included.
Unlike the previous incarnation of the module, this one now sits behind a 4HP panel and the layout has been slimmed down a bit too; there's a signal in (obviously) and a single CV input with an associated attenuator. Should you need to perform any additional calibration, there's a trimpot on the rear of the module.
These modules are built with Alpha 9mm potentiometers and Befaco micro knobs. The panel is fabricated from 1.6mm FR4 (PCB material)
Mounting hardware and a power cable are provided
