Is Elecraft seriously considering a KPA-1500 or KPA-2K?

I'd like to see the KPA-1500 use dual 1kw LDMOS transistors as they are
relatively inexpensive and can handle high reflected power. An antenna tuner
shouldn't be needed unless the SWR exceeds 3 to 1. I'd like the KPA-1500
designed for 2kw so it will easily make 1,500 watts in "run" mode all
weekend long on all modes, including RTTY. Too many of today's "legal power
amps" often won't make legal power. A quiet Amp is important, use 4" or
larger cooling fans and not tiny 2" fans like many solid-state amps use as
they often need to run at warp speed and then make a tremendous amount of
noise. I'd like two radio inputs and six antenna outputs, and to be able to
adjust the brightness of all front panel light from bright to very dim. The
KAT-500 front panel lights cannot be turned down low enough for me. The
KPA-500 is small and excellent for DXpeditions, build the KPA-1500 as a
robust legal limit amp with large heat sinks that will run cool, operate
quietly, and easily make 1,500 watts on all bands 160-6m and I'll be sure to
buy
one.
