Power transformer in a 12 volt/25 volt radio?
#9

Ok we can work with this.
Power transformer= 350 to 400vac ct @ 50ma., 5v@2a, 6.3v@ 1.5a or so.
Remove the 25L6 and replace it with a 12A6 (common war surplus tube).
Wire the 6.3v winding to the 6X5 and in series with the 5v winding. Phased properly you'll get 11.3vac. Connect that to the 12v heater tubes.
Wire the HV same as original.

When my pals were reading comic books
I was down in the basement in my dad's
workshop. Perusing his Sam's Photofoacts
Vol 1-50 admiring the old set and trying to
figure out what all those squiggly meant.
Circa 1966
Now I think I've got it!
