EN129 VCO

Voltage-controlled oscillator (8HP)

Based on:
EN129 Thru-Zero Oscillator by Dannysound.

BOM:
interactive version (top PCB)
interactive version (bottom PCB)

My version of Dannysound's EN129 Thru-Zero VCO. Functionally identical to version 1.0 (no Sync input).

Build notes

Something I'm very much not a fan of in this module is that the V/Oct input is normalled to roughly +3.8V, so tuning with or without a cable patched into this input is wildly different. Consider removing or kludging this out.
