Few power amps are rated for1.5kW continuous.  Yes, there are a few,
like some Alpha models.  Most are rated for 1.5kW intermittent duty, and
should be de-rated by a few dB for keydown modes.

The Ten Tec tuners I mentioned fall into that category too -- indeed,
there are a few fixed caps that will release smoke when run at 1.5kW
into some loads for long periods during a contest, but those caps are
easily replaced with parts rated for more current, and the replacements
are not expensive.

Folks should be more patient with Elecraft -- they are well known for
taking enough time with engineering both at the design and manufacturing
stage to produce a product we'll be happy to own, as Wayne's recent
post  in this thread clearly illustrates.
