Hey Johannes,
jeverything on the Polysix works except this OctaveSwitch. Waveform Switch is OK. I can change waveforms.

Thanks for the tipp. I will check this.

Greetings,
Stefan

 Does the Waveform switch work?
 
 Is it both in Manual mode and saved patches?
 
 There might be the connection on KLM-367 to connector CN06/pin3
 interrupted. You can check with a beeper or Ohmmeter: KLM-369/Octave
 Switch/middle pin to KLM-367/IC31/pin6.

  Hey guys,
 
  I have a problem with my beloved Polysix. The Octave switch died. My Polysix was repaired years ago from battery leakage. It worked flawlessly untill this day so I don't think the problem are after-effects from the battery disaster.
 
  I replaced the complete Switch Board with a spare part but the problem was still there.
 
  Then I checked at IC28 on board KLM367 if the Switch responds and gives the appropriate voltage settings. Everything is OK!
 
  I also checked the cable which runs from KLM367 with connector 5 to KLM366. Seems fine.Nothing is loose.
 
  Now I'm a little bit lost in locating the problem.
  It would be great If you guys can give me some tips.
 
  Greeetings from Germany,
  Stefan
