By any chance is anyone running an HF amp or transmitter with push-pull =
304TL tubes in the final? I have this homebrew here that uses this =
configuration. But the power supply it came with is in pieces and it is =
a mess. It was modified many times over the years by the builder and has =
been patched more than a Microsoft software product.

So this thing needs a filament, screen and HV supplies. I can use some =
of the original parts. But for the HV, I don't want to use the original =
design because it is built around a 230V pole pig transformer and has =
lots of quirky design anomalies that I can live without (Anbody need a =
125 pound pole pig? It'll give you 1700 to 2200 volts all day. The only =
drawbacks are that it is huge and weighs a ton).

So I'd like to cheat and see how someone else is powering their rig to =
get some ideas.  References to complete designs in any of the popular =
literature would be useful too. Can anyone help?
