I have an HF amp that uses a single 811A in grounded grid. The power
transformer smoked. The transformer was from an old TV set I think it
was rated at 540VAC on the sec and I ran it into a voltage doubler for
about 1300 VDC *. Any info on something I could use as a replacement
would be appreciated.

Ive got a couple of Variacs less the mechanical bits. I was
considering the possibility of winding a secondary on these.
