Hi Florian, thanks for adding me.
Basically some corrosion from a leaky cap had eaten some traces on the envelope/filter board. I posted on gearslutz about it
to get some "professional" opinions. Someone mentioned this M/P group so I figured I would join. I'm pretty new to soldering/electronics stuff, but this improved my confidence and interest in maintaining and repairing (at
least little stuff) synths.
best,
Paul
