Thanks Dave your input. I have actually already taken it to be
serviced. The headphone jack noise may turn out to be normal but in
any case, the actual output jacks will get repaired. Local off was
certainly not the case as I was able to get sound out of the
headphone jack. It is such a cool synth I can't wait till I get it
back.
