It's not a matter of "wanting" a higher line voltage ... you simply
can't pull enough current through a typical 120V circuit to provide
enough power for a 1600W *output* amplifier. Such an amplifier is
going to need about 4 KVA or around 35 A *average* and much higher
peaks even with a power factor corrected switching supply. The
120V wiring in your shack is certainly not up to that level ... nor
are the breakers, circuit panel, etc.

As others have mentioned, there were two amps built and put on display
a number of years
ago. One was legal limit and I think the other was about half that (I
remember more than the
current 500 Watt KPA500 though).
I probably would never spend the money for a full legal limit
solid-state amp but I might pay
for a kit amp. By "kit" I mean more of a kit than typical of
Elecraft's bolt-together kits. I mean
a real soldering kit with some SMTs already placed. Especially useful
would be the PA boards and
heat sinks already put together. But, other parts could certainly be
lower level kit pieces. Also,
the voltage levels are not too dangerously high (? 75 volts, 40 amps
maybe). Maybe the power
supply can be a separately priced kit.
Not even sure how much I would pay -- I wouldn't want ham radio to cut
into my book buying budget
for the year. Also, ham radio competes with my other hobby of wood
working. Those Shapton glass
bottom sharpening stones are getting pricey.

As a 6 month Elecrafter (k3+p3) I have never seen any discussion nor
requests for a legal limit compatible Elecraft amplifier with the
seamless attributes of the kpa500 . It would seem that the now
extablished 1000 w devices could form the basis for a commercially
viable amplifier. Perhaps no one else is interested, but I wanted to
ask if such a product is even on the "consideration" list?
