So i just got one of these from ebay and it didnt come with a power supply so i found one that matched all the specs 9v ac 500mA and connected it and it didnt turn on. I switch the polarity of the power supply, tried it again and now it turns on, but i can only hear signal when its bypassed.
It lives! I talked to them and he was as confused as we all are but he recommended me a power supply that for sure works from radio shack and its working now. I guess the psu i was using before was funky or something....i know sometimes you plug the right power into a pedal or something and it just don't work, i'm guessing it was that type of thing.
For future reference that power supply is part number 273-328 should any one need it.
