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.
