Quick question. On the 6BM8 power supply, the B+ is specified as 225v. I have my Hammond 269EX wired to my 120v mains using the white, or 115v tap. I am getting 238v for B+ and 3.5v*2 for heater voltage. I would guess that I need to rewire my input ac to the 125 tap on the transformer to bring these back in line.
Or is this 'clode enough"?

I get that the tubes are not identical. on further inspection I found that the voltage on pin 9 is vastly different.
217vdc on one and 125vdc on the other, and the diffference moves with the tubes. I suspect that I have a bad tube.
I DID drop these tubes onto the floor, so although they might have been bad to begin with, I suspect I damaged one of them.
Thanks for all the help, I will be replacing these tubes.
