I have the set fully assembled, non-working, with a couple of issues impeding my progress.

The overriding issue is too-high voltage. At 115VAC, the plate voltage for the 245 is over 300v, and over 700v for the rectifier. So, I'm doing my testing now at 60v or 75v and all the other voltages seem higher than expected--except the filament voltages, which are all good.

Is the transformer putting out too much voltage, or is it likely that I have made some wiring mistake? I've checked all the wiring several times, and it all seems OK except I'm uncertain about the RF transformers, but I'll ask about that later.
Thanks for looking,
Henry
