[Elecraft] [K2] Amplifier suggestions?

[W0FK]

I haven't operated an Acom, but note that it uses 4cx800's (as do a few other
companies). Those have been discontinued, and not having a future source of
tubes could be a concern. That's why Alpha switched the tube in its 8400
from 4cx800's to a 4cx1000's (new model is an 8410). 

The THP is a nice amp, but bear in mind that solid state amps are more
sensitive to SWR issues than tube amps. If you don't have good resonant
antennas, a tuner may be essential. I also found that the THP 1.5 required
100 watts plus from my K3 to drive it to full or close to full power,
whereas my PW-1 and Alpha 87A required a lot less for full output.

If I were looking for a non auto-tune tube amp, I'd seriously consider the
Alpha 8410, perhaps one that uses 3-500Z's (inexpensive and readily
available). Not sure where I'd go on an autotune tube or a solid state amp,
other than what I'm currently using.
