My filament draw is only .2 amps; and quite frankly; I'd those off batteries if I had to. But that has a 300ma 1.5V filament supply and 20ma b+ supply; the b+ draw is about 9ma. I think that transformer is only around $11; and the parts are small enough I could build where the batteries would reside. |
That's an interesting looking power supply. I already have some of the parts for it.
I'll use a power transformer from a scrap VTVM, that wasn't worth repairing.
I can always use an extra power supply for a battery tube radio.
