[Amps] Peter Dahl transformers

[Bill Turner]

Manfred, in spite of the problems for the homebrewer, I'm still interested
in switching power supplies for high power amps. 

Do you have any schematics or sources of design information for:

1. A 50 VDC 50 amp supply
and
2. A 3000 VDC 1 amp supply?

I'm looking for designs where the heavy lifting (engineering) has already
been done.

Thanks in advance,

Bill, W6WRT
