Well I have this amp going again, had some grounding issues with the 2 220uf 450 volt caps. Found some bad traces on the board where these 2 caps sit. Also found that 3 of the 4 output tubes were bad, I now have 24 hours since replacing the output tubes. I still have high heat issues with the power transformer. It gets over 120F after using the amp for 1 hour. I will post my changes to help drop those temps.
