> Or the switch or socket have failed. The capacitors and resistors = would not severe the current flow if they fail, as they shunt to ground = - if any, they would have to short circuit (in which case they should = show visible heat damage, plus some remaining voltage). The small = regulator would not affect the positive side of the supply regardless of = what happens to it, so it is down to the rectifier diodes or the = mechanical connection. >=20 > If you can't measure anything, anywhere, try to trace the voltages = with another 9VAC (lab) PSU im place of the original wall wart - if = there is a short circuit, the thermal protector in the wall wart might = cut off before you can measure anything. >=20 > Sevo Thanks Sevo - but see my follow up post from a few minutes ago. Now = that I'm actually supplying power to the wall wart (insert face palm = here), I'm getting the correct voltages, but still same behavior with = synth.... Though I'm still happy to keep debugging on my own, any recommendations = from anyone for a tech in the Boston area that could help? Dan=
