Supose transformers, unless army surplus, are not cheaper nowadays.

Objet : [Amps] power transformer
I'm looking for parts to build an inexpensive amp.
I'm thinking about using a pair of 811 tubes because the price is right.
Now the transformer problem: I have an unused TV transformer and would
like your opinions on whenther or
not it would work for SSB service using the pair of 811s. Transformer
has two plate windings, 300-0-300 volts at 250 madc and
250-0-250 volts at 280-0-280 madc, plus the usual 5 and 6.3 volt
windings. I figured with a full-wave voltage doubler I would be close to
1700 volts. But would the transformer rated 250 ma be sufficient for SSB
service???
