[QUOTE="Shinozoku, post: 156793, member: 1745"] Yes and no. I blew R3 on the power board. It is a 5w resistor. I replaced it and tried again, but it blew almost instantly. Same resistor. It seems to tell me there's a dead short to Ground somewhere downstream. I've checked the circuits around both places it goes to the tube board (preamp side) with no issues found. The schematics I was sent from Randall are not 100%, so I'm getting ready to trace down the last bit of circuitry past that resistor, though I'm not sure yet where it goes (only have tube board, power board, and schematics in front of me at the moment) I am almost certain it is not ether of those boards. That 5w resistor blows too quick for it to be anything but a short to Ground I think. I feel like I'm I'm getting close to figuring out this $@$_#@#$#@$# been very frustrating! [/QUOTE]
