There was; it was by a W9 who commuted to the WDC area (I met him once
for lunch) and IIRC was at least two, maybe three parts in QEX, in the
early '90s time frame.

There are some consumer microwaves that use AC/DC converters in switchmode.

We have commercial 10 kW Glassman switchers at work that put out 1500 VDC at 6 
Amps but they are not cheap. They power screen grid on TH628L RF tube.

Has anyone seen or heard of a Switching DC
Supply for Tube Amp use ?

Seems to me a way to get rid of all that heavy
iron.

I'll try to find it, But I do have a switching HV power supply design
here.? It was very nice design you would be able to set the output
voltage anywhere from zero to like 8K.

it was awesome!

If I find it here someplace I'll let ya know

Wow! this is cool actually!

I wish I would have tried this when I blew up the SB-220 HV
Transformer.

DJ7TL uses one as anode supply for his home brew 4CX3000A amplifier.
Its a surplus power supply which supplied voltage for a laser before.

Scroll down to the bottom of his qrz page:
