To the original poster: another option to consider is the OM POWER 2000A+
("A" for auto-tune). If purchasing new, it's less than the ACOM 2000A and
covers 6m. Single FU-728F tetrode, Auto-tune 2KW+ on CW/SSB, 1500W RTTY on
160-10, 1300W on 6m. The amp appears to be based on the manual-tune OM2000+
with the addition of a touch screen display and native Ethernet
connectivity.

If you run it at 1500 watts RTTY contesting, it will over heat after a
while, about 10-15 minutes as I recall."
Bill, was that with or without the externally-mounted muffin fan as an
assist to the blower? My 2000A was purchased in 1999 and the fan was an
option at the time. It was probably standard equipment in later models.
During my 12 months of ownership, the 2000A was never used on RTTY -- so you
bring up a good point.
There's an Alpha 9500 at a remote internet site owned by myself and N4CC.
It's a great amp for this purpose. We use the internal RF switch as an
antenna selector and AlphaMax mostly keeps tuning where it should be
although from time-to-time, we see a lot of "hunting." However, it's an amp
I would not have on my home desktop: too much blower noise and the T/R
relays are ridiculously loud. My 2000A was very quiet in operation although
perhaps that may be one reason why it's sub-par on RTTY.
