Binary files /dev/null and b/3D Printing/Panels/Radio_shaek_standoff_padded.stl differ Binary files /dev/null and b/sr1_full.png differ aac0a4a5b4 Notes from MK's PCB livestream Footprints: - 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.
