Warning

its very important  to use shielded cable for VCO I/O connections to the sub vco boards (dont forget to ground the shield ob both sides)

for wiring to switches dont drill the cables, otherwise you get softsync issues.

dont drill the cables for the switches ! or you get some soft sync.

its a difficult MOD and there´re few risk to destroy your rare trannys (2N4125, 2n5459, CA3046) if you do it wrong.


for all users who got my TTSH SYNC PCB, only use the resistor values as shown (the VCO SYNC Version2 PCB use a different PCB designator layout)
