Dlx Rvrb, 360v vs 450v plates

[Craig B]

I used the same PT with my modified deluxe reverb. Needed to use the 125 volt primary wiring to get the heaters to 6.5 volts. I have 1 fewer premp tubes to draw current. Get 348 B+ volts with a Sovtek 5AR4. I prefer the slightly softer sound of 404 volts with a 5R4GYB and adjusted string dropping resistors. Using JJ 6V6s and they sound fine at either plate voltage.
As stevem said,
How do you want / need the amp to sound?

When do you want / need the amp to clip?

My Weber build 6a20 Deluxe Reverb Power tranny has Red/Red 680V, Red/White 540V taps.
...
My choice is 450v on the plates or 360v.

I used to own a 1964 Deluxe Reverb. It had 394v on the 6V6 plates and 6.3v on the heaters when fed 120vac to the power transformer primary.

Turns out the voltages marked on Fender schematics aren't "absolute truth." And I would personally opt for "lower voltage" any time I have to choose between higher or lower voltage.
