I wired it to a Zenith 5-S-320 and the radio ran fine. I still get 128 volts and the output from the socket read 121 volts. Maybe I'm expecting too much since the radio really has no chance of loading the transformer.
The next question is, so what? 128 volts goes into radio transformer and the plate to plate voltage voltage supply rating for the 6X5GT is well above the stepped up voltage it should see. Will it shorten the life the the heater filament if the voltage runs at 6.6 rather than 6.3 volts? I don't know. That would be my biggest concern. How will the tube heaters hold up. If there is little or no harm for the few hours I would run the radio at 128 volts I wouldn't expect a serious problem.
Thoughts?
