I've got an old power transformer that is meant for a tube amplifier. It
has 3 filament windings and one HT secondary. Running the primary direct
from the wall supply, 120v, the HT secondary with out a load is 655vac
across the outer legs. It has a center tap that I ignored for this purpose.
So, I can guess that 327-0-327 is probably 300-0-300 give or take 10-15v.
The hard part is figuring out how much current capacity exists without
killing the transformer.
I have tested with 10W...
find mA rating for unknown power transformer?
