- wrong Silkscreen for matched pairs
- wrong Silkscreen or polarity for Capaciator C20

change the polarity of C20 10µF elecrolytics (its the right hand capaciator)

due to VCO Bleed issues, Nordcore from muffwiggler sales VCO Regulator pcbs, this fix this issue. approved
- build the VCO regulator
- desolder or cut the MLCC 100N from the power inputs on all 3vcos and from voltage processor, the 10uF caps can leave out too (but its okay to have this)
- drill a hole in pcb to mount by a 10/12mm spacer the pcb.
- put a further spacer on the 10/12mm spacer for calibrating the VCO regulator (dont connect the regulator to the vco header yet.
- connect only power input to regulator and set it to 14,6V (TP1+ TP2, TP1+TP3)
- unmount the second spacer and place the regulator in MTA header for final calibration/further tesing/building.
