[Elecraft] OT: THP 2.5KW amp

Don't forget the fan usually comes on when you transmit on the Solid State
stuff.

Interesting that you thought that the fan was quiet.  I couldn't hear
it either, but then again, I would be hard pressed to find a noisier
place than inside the arena at Dayton.

I say "interesting" because I asked about fan noise.  The THP person
there (some American guy, hence language no issue) asked me what kind
of operating I do and I replied, "Contesting."  He was glum and said
and said that the fan would be far too noisy for me.  Honesty is good!

However, in this month's QST is a review of another THP amp by K1RO
(another contester) and his review also said "quiet fan."  Of course,
it was a different amp, and he did not use it during a contest, but
one might figure that the fan is the fan. At least they kinda look the
same!  :-)

I went back the next day (he didn't recognize me) and I asked if they
were working on a quieter fan, and he said that they are indeed
working on it.  YMMV.
