The CL- 80 has no bearing on the ratio.
You can try adding the resistors in SERIES to determine the value, but don't do that permanently.

Your transformer at 125 VAC should be fine. Can't say abt CL80, as the were only used on the solid state rectified amps, afaik.Okay great. In series!
I changed the 12ax7, and at 110v on my variac all voltages are within spec for both amps. Including -46 on the output tubes, and -46 on the 12ax7. All at 440v
Is it necessary to change resistors, or can I just run my variac at 110v? Again, my transformer is at 125v

Check the heater bus twin for 6.3 VAC to confirm. If high, go to 125VAC tap.Gotcha.
Just to be clear, I'm fine using the 470ohm resistor in series with the diode, since everything is good at 110v. And I don't need to change the voltage tap on the transformer, right?
With the variac, but why bother? He best just wire it 125 volt tap and leave it be, imo.Yes, It's fine to do that, but if you are going to run it off of a variac permanently you might as well just go back to the 117v tap.
Try measuring it at the amp. I'm very interested in your project's success.
