Hey all,
I got a pair of Golden Age pre 73s on discount from Musicians Friend. Both were missing power supplies but only one seems to be slightly faulty. Here's the deal: when powered on, the signal LED lights up and there is a constant, low hum. I poked around with my DMM and I got a reading of ~35v on the 24v pads. I turned the trimpots and something started smoking...it seemed to be coming from the 2N3055...
Mine is similar to the one pictured below, but the power supply pcb is a different revision
Thanks for any help
