      Hello fellow synth enthusiasts!



I've spent (literally) years restoring my Univox Minikorg 2 and I'm down to one last lingering 'issue'..



There is often (30-40% of the time) an audible click (or snap) when

depressing and/or releasing a key. The click sounds the same whether the filters are totally closed or open, so it must be happening after that stage (and probably in the VCA/Envelope?).



Here are the easy-to-read schematics:

I really hope someone has some idea!?



Thank you very much!
