This amp has a 5V6 on a variac, and maybe a lowered B+ is affecting the power output.

How about a voltmeter on the B+?
Also it will be interesting if you find a different output transformer to compare waveforms.
Congrats on your success so far.

All power output measurements are being done with the Variac turned up all the way which puts the B+ at 336 Volts.

It would be interesting to see how a different output transformer changes things (if at all). That little experiment will likely have to wait until after the holidays. I will be sure to post the results when I do it.
