I agree with the Techs,I've seen many opamps go bad over the years,but I remember changing Opamps back when these vintage synths were still relatively new.I think everybody missed a key word in the original comment,this was from an engineer,engineers don't get into the real world of repairing the things they design,I don't know any Techs that haven't at one time wished that the engineer that designed something would be sentenced to work on the something for eternity.such as the engineers that designed the new Hammond Suzuki Leslies,where everything is engineered right to the limits without any headroom like the older Leslies had,and the sealed speaker enclosures inside Gulbransen or Lowrey organs,I've been running into a lot of them where the speakers have the foam rings deteriorate and fall completely apart,the speaker boxes take over an hour + just to get them apart and another hour + to put back together,making a simple speaker replacement with parts and labor into a $300.00 + job
