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 pin Molex connector 2.54 mm spacing"/> 100V 0.15A standard switching diode, DO-35 | | | J9 | 1 | Conn_01x04 | Pin header, 2.54 mm, 1x4 | | | | C7, C12, C13 | 3 | A1M | Potentiometer | | J4 | 1 | Conn_01x10 | Pin socket, 2.54 mm, 1x4 Light emitting diode | | Q1, Q2, Q3 | 3 | 22k | Resistor | | | Tayda | A-1847 | | R17, R19 | 2 Fireball/Fireball.kicad_prl | 2 | 10R | Resistor | | | | | | | | C6, C7, C8, C9 | 1 | B20k | Potentiometer | | R6, R8 | 2 pin Molex connector 2.54 mm spacing Pin header 2.54 mm 2x5 | | J1 | 1 | Conn_01x10 | Pin header, 2.54 mm, 1x10 Pin header, 2.54 mm, 1x2 (see build notes A-1605 * Fit SIP socket only if you need a noise generator, but contains one?

Change page size to 9mm and align it precisely for repeatability Change transistor footprint to inline_wide, fix DRC ground plane Updates from real TL0x4, fix pots being backwards.
