So I had a faulty barrel plug on my Total Recall, so I swapped it out (wires are oriented correct, positive center). I plug in the PSU and turn it on, heard a loud pop, and now the pedal is dead. I checked the voltage on the EHX power supply, and I'm reading 33 volts DC. Could that have fried the board? If so, what are the likely components I'd have to replace? I'm assuming the LM7915, but is there anything else I should be looking hard at? I'm thinking maybe the 1N4751a as well, as it's only rated to 30v?
