The bias will adjust just fine with no signal. For now I have the outputs at about 40 mA each. At low volumes all seems well. Once the volume is raised the bias reading starts to go up and down and will not stabilize. The harder you push it the worse it gets. It is worse in one channel but both are affected. I changed out the bias supply caps thinking they were bad (although new and tested fine). Not the problem. Tried a new set of output tubes. Not the problem. Checked voltages throughout the amp and everything seems fine. Looked for bad solder, bad grounds, wrong wiring. Nothing shows up.
So please if you have seen this issue before please respond with some help. No thank you to a new board. Or further modifications or additions. I want to fix this in original design state. I have gone so far as to check the voltage drop across the output tube grid resistors to see if something is off. Seems fine.
Any constructive help is appreciated. Thanks WLT
