I have an HF amp that uses a single 811A in grounded grid. The power

about 1300 VDC *. Any info on something I could use as a replacement
would be appreciated.

I was thinking of using this transformer for the same purpose.
I assume this is the single 811A amplifier in the 1967 ARRL handbook?
If you use this transformer you can put the secondary windings in series
and use a bridge rectifier instead of the voltage doubler. *You will get

transformer might be able to handle TWO 811A's in parallel if you want
to beef up the amp.

Yes that is the one, more or less, Back when I was in high school I
built it as a CB amplifier in my junior year 69-70, Im so ashamed. I
do have another power supply I might could use with it. Its built in a
rack mount chassis and would not be my first choice. Ive found 200W
PEP to be more than adequate but I may consider that option. I wanted
to complete the amplifier by adding the rest of the ham bands.\\
