Although I’ve only run my 2000A in one RTTY contest, my experience has been
different.
I have a tuned antenna system, so the amp always sees a perfect match to the
feed line. Under that condition the Acom 2000A ran 1500W RTTY without
complaint and without overheating.
I also have a 9500 and does as well with RTTY, too. I prefer the Acom 2000A to
the 9500 simply because the latter is way too noisy on CW due to undamped relay
noise. YMMV of course :)
