My mistake, I guess.  I run an Alpha 9500.  A true 1.5 kW tuner is important
to me at least.

Good to hear. But if a tuner is advertised to handle 1500 W, it should do so
without user mods.

The original poster talked about 1500 W.  Is Elecraft considering such a
tuner?  That would be new (and great!) news to me.  For some reason I was
under the assumption it would handle around 500 W.
