Could there be a middle ground where a KW SS amp can come in at an

I suspect this is hard to do. Although a SS amplifier itself is simple,
by the time you get the power supply, the protective circuitry, the
pretty-much mandatory antenna tuner, etc., the price climbs.
I have another idea. Personally, I don't want (another) KW+ amplifier.
Too big, too much money, and too much RFI potential (I know, it's not my
fault, but I still hate those phone calls).
But an extra 6 dB would definitely make a difference in pileups and
marginal conditions.
What I want to see is a 400-watt "KPA400" to *replace* the KPA3 100-watt
amp in the K3.
It would require beefing up the KAT3 and possibly the heatsink and fans.
It would be best to run it on 48v or so; that would give better IMD
performance on SSB and make the current draw more reasonable. Possibly
Elecraft could also sell a 12/48v power supply. It would also be
possible to add a class-A mode for SSB for even cleaner signals.
The main thing is that I think this could fit in the existing K3
package, which would make it *very* appealing.
