Expanding on W9GE's list, here's what I've come up with over the years as to
why I might want a newer amp:
1. I want to run the amplifier on 160.
2. I want to run an amplifier on the WARC bands (that allow it) with
reasonable tank circuit efficiency.
3. I want the built-in QSK of some of the newer amps.
4. I want to automate the band-switching of the amplifier (for instance, to
make sure it's always on the same band as myr transceiver or exciter when I hit
the key or the PTT switch).
5. I am bothered by the fact that older amplifiers in the USA were designed
against an FCC 1KW CW INPUT limit (versus today's 1.5KW OUTPUT limit).
If none of the above are of concern, a Heath SB-220 is excellent value, in the
US$500 - 700 range the last time I looked. I'm sure there are many other
brands and models, too -- I just happen to be real familiar with the SB-220,
since I still use one.
