Thanks, xaudiomanx. I think your initial suggestion was where I am headed, i.e., as I understand it, the positive bias supply has a resistor after the rectifier so, perhaps, increasing this value would reduce the current on the positive side allowing these higher-current-drawing tubes to be biased correctly. I thought, maybe someone had a similar issue and performed a similar fix. I definitely appreciate the feedback and suggestions. I think I will see if I can return these tubes and purchase another set (hopefully they will take them back) elsewhere before performing any changes to the bias circuit.
