[Elecraft] Linear thoughts

I hate to interrupt the group fantasy but,

No way a "1500W key down forever any mode" solid state amp is going to 
be quiet, affordable, or fit in the KPA500 box, much less the K3s (that 
was funny). Add an internal tuner capable of "1500W key down forever any 
mode" and the box gets bigger, the fans get louder, and the price goes 
up. If you're planning on running this on 120V...just stop.

A power supply capable of "1500W key down forever any mode", 50V stiff @ 
80 amps, isn't going to be light, quiet, and not be a switcher (that was 
funny too).

Remember, the prime directive is 160-6m "1500 W key down forever any 
mode". There isn't an SSPA for sale in the amateur market that can do 
that. So...you're paying $8K right now to get "close" (close is 
relative). If Elecraft can do it for 20% more good on 'em. Then you get 
to decide good down payment on a new car, or KPA1500.
