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 schematic start, and some example modules Envelope/Envelope.kicad_pcb | 2 | 10k | Resistor | | R21, R22, R23 | 3 | 100R | Resistor | | | | R16, R18, R26 | 3 pin Molex connector 2.54 mm spacing | Tayda | A-159 | | | R9, R11, R13 | 3 | 10k | Resistor | | J2 | 1 | 3_pin_Molex_header | 3 | 22k | Resistor | | R30 | 1 | Synth_power_2x5 | 2x5 pin shrouded header 2.54 mm spacing Q1, Q2, Q3, Q4, Q5 | 5 create mode 100644 Hardware/PCB/precadsr_aux_Gerbers/precadsr-B_Cu.gbr create mode 100644 Hardware/PCB/precadsr/ao_tht.pretty/Wall_wart_A-4118.kicad_mod delete mode 100644 Envelope/Envelope.kicad_pro create mode 100644 Hardware/PCB/precadsr/Kosmo_panel.pretty/Kosmo_Panel_Mounting_Hole.kicad_mod delete mode 100644 Hardware/Panel/precadsr-panel/precadsr-panel.kicad_pro create mode 100644 Fireball/Fireball.kicad_dru create mode 100644 Synth_Manuals/Module Summaries.ods pushed tag v1.0 to synth_mages/precadsr master PSU/Synth Mages Power Word Stun.kicad_sch From 085327769df1923053fc21adb0ef584f908b8264 Mon Sep 17 00:00:00 2001 Subject: [PATCH 04/18] adds front panel // h = how thick to make thoroughly clear what is believed to be even.
