Dick, such reproducible cookbook reference designs will inevitably appear in
the ARRL Handbook or a QEX article one day; already a capable 250 Watt SS
amp with decent specs was published in a recent edition. There's certainly
a lot of isolated ham shack experimenting with bespoke solid-state seriously
QRO HF amps going on and someone coming out and publishing a general design
and construction article would surely be imminent.

I haven't seen anything in print that would let me build something like
that. While I have built some tube amps and converted some to 6 Meters, I
don't consider myself an RF Design Engineer, so I would need something
to go by. I have no qualms about taking a crack at building one, but I
hesitate to embark on a "blank sheet" design.

Dick, there's no need to wait for such innovations in RF power
semiconductors as such a long awaited low cost S.S. 1.5 kW HF amp can be
economically homebrewed using a readily available multiplicity (6 devices in
parallel/push-pull) of cheap 50V RF MOSFETS sourced from the surplus market.
The overall BOM will not break the bank, and such a rewarding project is
well within the scope of the tech-savvy ham experimenter (that rarefied
breed that remains amongst us in 2013, as distinct from the ubiquitous
appliance operators).

I doubt I'll see this filter down to Ham Amps in my lifetime. I'm still
waiting for a decent SS Amp that runs 1.5 KW out and does not cost a
fortune.
