Steve, you are correct. I confused myself! Calculations at 1:00 in the morning.... Yet my output voltage for the filaments are as I listed them. Therefore, the original filament voltages must have been higher yet, perhaps compensating for internal resistance losses. My tubes will run cooler and last longer, but weak tubes will be less effective. Oh well, best laid plans...
