Ok, I just had my adcom amplifiers fixed. I sent the boards and the heatsinks w/o ps or case off to be fixed. I seem to be back to square one however..... I'm still getting - 54v on the speaker outputs and -6v on the other output. I'm thinking that I hooked up something poorly, but there are literally only 5 wires to hook up + indicator LED's. per channel. Its not like I haven't built amps and power supplys before. None of the output transistors leads are shorted to ground, and supposedly all the outputs were changed (not cheap). If I take the rail fuses out of the amp, the voltage on the outputs goes away (like I'd expect...but just in case I REALLY wired something wrong...had to check that) any ideas other than completely replace all the transistors again?

You don't know that you have any broken transistors.
