Alpha pots: tight, only 1/2 turn for nut 11mm - rotary, SR2511 style, with very large range of in-tune response, but comments discuss potential fixes, maybe worth it for a drone / manual version, https://kassu2000.blogspot.com/2018/07/avalance-vco.html for a box film cap for 100v is smaller, but not to front panel and pcb into different files Add a front-panel PCB Subject: [PATCH 2/2] Update README.md 3d0ca7fdf6e2ad8d7864221e585c668e46544055 Update README.md 5ff3077e8252367b7eceb0b21b0803904b695d42 bacdac34d747275148c56e8293dc209c2e326fe4 c9e81f0cc630cea052574ce7c50b3e82145bb626 2bd01a1ff2d30ca3cff647bbf3b80645437cc07c start 744b72ef7e0d94fccfae99ec3cb3514981ac4616 Add simplest muscescore example 744b72ef7e0d94fccfae99ec3cb3514981ac4616 2dd0b8c0c736720a0b064bbe1304dc9562beb260 Latest commits for file Docs/precadsr_layout_front.pdf Panels/dual_vca.scad Normal file Unescape Hardware/PCB/precadsr/Kosmo_panel.pretty/fastestenv_Panel_Mounting_Hole.kicad_mod Normal file Unescape Hardware/PCB/precadsr/Kosmo_panel.pretty/Kosmo_Panel_Slotted_Mounting_Hole_NPTH.kicad_mod Normal file.
