Apologies if this is a repeat message, but I sent it yesterday am, and
still haven't seen it come thru, so I thought I'd try again.
I just ran on to a HB power supply that looks to have been built for a
tetrode amp of some sort, with hollow state electronic regulated 350V
screen supply, etc.
However, I don't know the actual ratings on the plate xfrmr, and the
power supply needs several electrolytics replaced, etc before I can
bring it up.
My question is, does anyone know the specs on a Thordarson T-21P83 plate
xfrmr? I have checked the catalogs that I have been able to find,
including the 1938/39 and 1942, as well as the newer Catalog #76, but I
don't find any reference to this puppy. My guess is that this thing was
designed for a half gallon amp, but the screen supply is much too large
for that, and the plate transformer also looks to be a little large for
a half kw, so I could use some help if someone has a catalog that lists
this thing.
Many thanks in advance,
Don
