DXing, contesting, or satisfaction, that extra 3db sometimes makes a a
big difference!

There are a lot of over rated amps (by the manufacturers) on there, that
are not capable of running that much power without self destructing.
Legal limit amps that are only good for that on low duty cycle that
receive glowing reports.
But look for problems, or patterns and if they are prevalent in a
particular amp.
An occasional "Terrible service, or bad attitude" may not mean a lot.
Most of us have known people who couldn't give a complement with out
upsetting the recipient. People answering telephones often do not
respond well to this personality.<:-)) A polite approach will often get
outstanding service.

/enough/ reviews, you can get a picture of the overall degree of
satisfaction with a product. So here are some of the average ratings for
in-production amplifiers with a reasonable number of reviews, both solid
state (the first 7) and vacuum tube:
Amplifier Reviews Average rating
ALS-600 146 4.2
ALS-1300 55 3.8
Elecraft KPA500 65 4.9
SGC SG-500 36 4.3
SPE 1K-FA 77 4.9
SPE 2K-FA 24 4.8
Yaesu VL-1000 70 4.3
Alpha 9500 108 4.9
Acom 1000 147 4.9
Acom 1010 46 4.9
Amer. AL1500 67 4.8
Amer. AL80B 119 4.6
Amer AL811H 159 4.5
I think it is significant the NO other amplifier with more than a few
reviews has an average as low as 3.8 (the Dentron 160-10 has 16 reviews
and a rating of 3.6). I would think twice about buying an ALS-1300!
If I wanted a lower-powered amplifier I would look at the Elecraft or
SPE-1KFA. The SPE-2KFA is an excellent choice for a higher power
amplifier, although it is more than twice the price of the ALS-1300!
If the guy needs high power but is constrained by available funds, then
maybe he should look at a tube amplifier like the AL-1500, which is a
few bucks cheaper than the ALS-1300.

Looking for info on these SS amps. ALS-600 vs ALS-1300. A ham ask me what
one to buy ? I have no experience on SS amps.
I did tell him not much difference in S units between the 600 vs 1200 w .
Any thoughts ?
Thanks de John KØCQW
