RE: [vintagesynthrepair] Micromoog problem

It's not necessarily that a note is triggered, just that the VCA is for some 
reason stuck on.  Check the gate signal from the keyboard and the control 
voltage going into the VCA, it should narrow the search down a lot.  If you 
don't have a service manual it will be a bit more difficult...
