Vintage Synth Repair

Check the fuse on the psu board, the output circuits are fed from a +15v
supply whereas the digital side of things is fed from +5v let me know if you
need anymore help and i'll scan the part of the drawing that you require . I
wouldn't want anyone else being ripped of by the guy at Analogue solutions,
who sold me for ?30 a very very poor photo copy of the service manual.

  I have a similar problem with a Poly61M. It send midi data, but its
  internal sounds lock up. I've sent it out for repair twice to no avail.
  Any hints would be greatly appreciatred.
