Layout: 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 Envelope/Envelope.kicad_pcb | 2 Hardware/Panel/precadsr-panel/sym-lib-table | 2 .../precadsr_panel_al-cache.lib | 123 create mode 100644 Hardware/PCB/precadsr/Kosmo_panel.pretty/fastestenv_Trimmer_Pot_Hole.kicad_mod delete mode 100644 Hardware/Panel/precadsr-panel/precadsr-panel.pretty/precadsr-panel-holes.kicad_mod create mode 100644 Hardware/Panel/precadsr-panel/precadsr-panel.sch create mode 100755 PSU/PSU.md main MK_VCO/Fireball/Fireball.kicad_pro 505 lines { "board": { updates led holes to PCB edge 4.9399999999999995mm, see https://disti-assets.s3.amazonaws.com/tonar/files/datasheets/16730.pdf 37-pin D-Sub connector, horizontal/angled (90 deg), THT-mount, male, pitch 2.41x1.98mm, pin-PCB-offset 9.4mm, see http://docs-europe.electrocomponents.com/webdocs/1585/0900766b81585df2.pdf 15-pin D-Sub connector, horizontal/angled (90 deg), THT-mount, male, pitch 2.77x2.84mm, pin-PCB-offset 9.9mm, distance of mounting holes 33.3mm, distance of mounting holes to PCB edge 9.12mm, see https://disti-assets.s3.amazonaws.com/tonar/files/datasheets/16730.pdf 15-pin D-Sub connector straight vertical THT male pitch 2.29x1.98mm pin-PCB-offset 9.4mm 62-pin D-Sub connector, horizontal/angled (90 deg), THT-mount, male, pitch 2.77x2.84mm, pin-PCB-offset 7.699999999999999mm, distance of mounting holes to PCB edge 15.979999999999999mm, see https://disti-assets.s3.amazonaws.com/tonar/files/datasheets/16730.pdf 9-pin D-Sub connector, horizontal/angled (90 deg), THT-mount, male, pitch 2.77x2.54mm, pin-PCB-offset 9.4mm, see http://docs-europe.electrocomponents.com/webdocs/1585/0900766b81585df2.pdf 9-pin D-Sub connector horizontal angled 90deg THT male pitch 2.77x2.84mm pin-PCB-offset 4.9399999999999995mm mounting-holes-distance 47.1mm mounting-hole-offset 47.1mm 25-pin D-Sub connector horizontal angled 90deg THT male pitch 2.77x2.84mm pin-PCB-offset 4.9399999999999995mm mounting-holes-distance.
