A lot of great suggestions but two I have not seen discussed:
1) I really like the idea of a separate power supply simply because if
the amp has to ever go in for service or be shipped it is a lot easier
without a heavy power supply inside the cabinet. Just send the RF deck
to Elecraft.
2) I like the idea of an optional INTERNAL tuner. Makes it nice and
clean for those that need a tuner without a rats nest of Y cables, etc.
If there is going to be an external tuner make it weatherproof so you
can put it OUTSIDE.
I would love a 1.5K+ amp with a K3 type legal limit tuner I can put outside.

The "KPA1500" should look, feel, and behave like a KPA500. OK, it can
weigh a little more but should be liftable by your average age ham
[oldish]. If you want to sell it widely, the "KAT1500" will also be
needed since there are a whole bunch of folks who have less than
monoband stacks on all bands, but it needs to be either an internal or
external option, some won't need it.
Fans should make no noise whatsoever, even on high speed. Rated for
100% duty cycle to accommodate RTTY, JT65, and 75 meter AM looong
transmissions. It shouldn't cost more than 3 times a KPA500, same
$/watt. It should accept higher VSWR's than the KPA500, say maybe
3:1? A plus would be operation on a 20A 120V circuit and/or a sagging
generator. Needless to say, full perfect QSK at 110 WPM, zero IMD,
and be able to eliminate TX phase noise if used with some notable
non-Elecraft transmitters. An LCD display for a trapezoid pattern to
assure linearity would be a plus but not essential since it's going to
be perfectly linear anyway.
Very tough market to enter, and potential customers can be so very
fickle.

PS: Before blood pressures rise, paragraph 2 is a feeble [very]
attempt at some humor based on passages on this list. A deep breath
or two would be best. I believe paragraph 3 is true however, and I
really want to see Elecraft stay in business.

Folks, if we did introduce a 1500 W solid state amp similar to our
KPA500 in operation, what features etc would be important?
