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.

There's an ample supply of used xfmrs at PTOP oldradioparts.com

I recently got one for my homebrew xmtr. You might have to buy some
other stuff to reach the $20 minimum order. I have never failed to find
other things that I 'need'.
