Expert electronics opinions needed: Radiola 60

[Electronic M]

For now don't connect any wires leaving that trans to each other (especially ones from the same winding).

Assuming the Radiola has good filament voltage to the 80. All you need to do is swap rect plate windings, power the admiral trans line winding off a variac, and meter it as you increase the voltage. Once B+ is at factory levels measure the variac output. depending on what it is there are ways of using multiple windings and or the two transformers in tandem to get AC inputs that do not match line voltage.
