Vintage Synth Repair

sounds like filter is set to high resonance as its in pitch and is tracking pitch

see if you can adjust the resonance and if it has any effect

  I'm having problems with an SH 2000 , it has this hi pitch squeal whenever I play a note.
  It's in pitch so it's not some random noise.
  It's still there when I turn of all presets ?

  PSU is recapped.

  Any ideas?

  Thanks
