[Elecraft] Amplifier suggestions?

[Maarten van Rossum]

Let's say, for argument's sake, I too have a THP 1.5 (which I do not). My
work and family take up most, if not all of my time. I can only put a couple
of feet of wire to use as a antenna because of HOAs. I have 10 countries
confirmed because I don't care for QSL cards or LOTW.
Does that make it a bad amplifier? I hope not.

I don't actually own a Acom 1000 but have used one for many hours at our
contest station or during field days. We Also use a ACOM 2000. Both
amplifiers are very good and near bullet proof. It has a very good
protection system which shuts down the amp if something is wrong. That said,
it will take a wide range of SWR without shutting down which makes it easy
to use because you don't have to retune it every time. If you do have to
tune the 1000, it will only take you a couple of seconds because tuning is a
breeze. The 2000 is fully automatic so you tuning that monster is even more
easy.

Our amps get a lot of use and abuse but up till now we never had a problem.
To give an example, last year we went to OZ to participate in the IARU
region 1 field day with the OZ5GX group. I had met them a year earlier
during summer holidays. During the field day we obviously used a generator
to power our equipment. It was a Diesel generator which provided 380 V.
After some rewiring we got 230 V which we needed for our equipment. After a
couple of hours something went wrong and the Acom started to shut itself
down repeativly and on the display it showed a code of letters and numbers.
I grabbed the manual to find out what it meant. I quickly found out it meant
"High Voltage" so I decided to check the voltage at the power outlets. The
multi meter showed 270 V (!). We quickly switched off all equipment and the
generator. None of the other equipment showed any problems but thanks to the
Acom we new that something was wrong and were able to fix it before any
damage was done.
As for the THP, I never used one so I can't comment on that amp.
