Yeah, apparently they prototyped a single tube (can't remember what the final was) KPA-1500 years ago ..but never went anywhere with it. I have the KPA500 and an Expert 2k-FA and they both play perfectly with the K3. The KPA500 is about half the weight, a third the price, and much much quieter. High power solid state is still newish technology for Ham Radio application. Also remember, that a lot of the world has 400-500W output limits, so the market for higher power amps is somewhat limited. I had discussed with the Elecraft folks when they were at Seapac last year.

The first 500 watts is the best 500 watts you will ever use...
