Hi all, I’m new here…
I have purchased my second Minimoog Model D recently. The first one works perfect, second one had a problem… no sound.
One capacitor was exchanged - it works! 
But..
If one, second, third key pitched, it doesn’t matter which one, I hear whole time the same sound.
Keyboard cleaned, busbars cleaned, I have even connected the keyboard from my first Moog - the same sound by all pitched key coming again it doesn’t matter which key pitched… ok, I have connected all boards from my first Mini over cinch jones - the same problem. No idea what could it be… any ideas?
