Check the connections from the Tail of the PI (56K) to the feedback switch if you have one. It could be that you aren't gettin a ground on the PI.

OMFG!!!

You nailed it!

All Voltages are 100% under control.

I seem to be running cool on ALL volages... Is that because of the 1k5 resistor at the cap can?

Or is it because I am using Electro Harmonics that eat up more current...??

That one was pretty easy......glad you found it! 8) The voltages on every amp are different. They should be in a range but with different trannys,caps, resistors and tubes there is always tolerances that come into play. As long as they are close I wouldn't worry about it. I would rather be running a little cool than have the problem of how to get the voltages down.
