[Amps] power transformer

[Tom Bowman]

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???
