In whole or in part through the board, cross at 90° to minimize capacitance between traces - .3mm for non-power lines, .6mm if carrying power 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 Latest commits for file Dual_VCA.diy Add VCA shaek layout Add schematic, start on PCB 398c2b234c Checkpoint after tweaking footprints some more, starting over at 14hp PCB initial layout, no traces "silk_line_width": 0.15, "silk_text_italic": false, "silk_text_size_h": 1.0, "silk_text_size_v": 1.0, "silk_text_thickness": 0.15, "silk_text_upright": false, "zones": { "min_clearance": 0.5 } }, updates to rev 2 Battery clip for batteries with a wire.
