General discussion on the future of ham amplifiers, either tube or solid state

General

A KISS tube or solid state amplifier

I would like a solid state legal limit amp, which is reasonably priced. What they are asking for some of these amps is atrocious, I paid less for my first car than for what they want for amplifiers now a days. Even tube amps, some of the prices are simply outrageous on tube amps. Make it on the KISS principle, somebody has to have a nice amp at even 1KW that doesn't cost a small fortune.

Amp Suggestion.

Support for software defined radios, for example pulse step modulated IGBT based switching high voltage power supply (see http://www.j-hawkins.com/am.html), internal direct digital synthesis master oscillator (optional) and in-phase + quadrature modulation (I+Q) to support unlimited operating modes.

Built-in SO2R

Honest-to-God SO2R capability where two separate tuned inputs are switched to their own tuned outputs to share the RF deck across two different transceivers on two different bands. Share the expensive tube, power supply, and protection circuit while effectively doubling the input and output tuning circuit

Integrated receive filters.

Integrated receive filters, build in the model 419 filters for tx and rx, or a better rx only filter like the w3lpl design.
