AoKicad and Kosmo_panel, which provide needed libaries for KiCad. To clone: submodules avoid non-circular holes in footprints whenever possible; some fabs charge more for ovals - make power connection traces larger; MK uses a CA3080 OTA, an expensive and rare chip these days ($3/ea on amazon, maybe fakes) VCA MK's VCA Probably a straightforward build: one op-amp, four transistors and some example modules 811ef45c764021f623b8bb59234df1314fce4e91 12V, -12V and ground needed, probably up to it.
