OT: new SS amps

DOUGLAS ZWIEBEL
I just ran into this by accident.

http://www.ameritron.com/catalog/Ameritron_2009.pdf

See page 9.

No stated expected delivery
Not enough "specs" for my liking, but still, rather interesting.
Is this "contest grade?"  Who knows?

I have no vested interest in this company.

In reply to this post by AC7AC
Ron, there are other considerations.  The tubes available today are made in China.  I had very bad luck with two sets of Taylor brand 572Bs that were made in China.  One set never worked at all and the other set lasted about a month.  I am still using the 572Bs that I bought in 1976 used.  So, if you get one of the 811A or 572B amps with Chinese tubes how long will they last?  Am I extremely unlucky or did I ruin them intentionally as R. F. Parts accused?  I really don't know, but it certainly will weigh heavily on my decision of what amp to buy.  In fact, I just bought a used ALS-600.  I will see how well that works for me.

Tuning is not really a factor for me.  If you buy a "No Tune" solid state amp then need an antenna tuner you have not changed things a lot.  But, will you need new tubes in a month or so?  How long will you be able to buy them?

Sandy, did you ever take a look at what a kilowatt amp cost in 1955?  It would be more than than $3,000 when $3,000 was a year's pay for most.

Re: OT: new SS amps

That is why many hams built their own amplifiers back then - a pair of
813s could be obtained for $25 or less back then and there were surplus
transformers available at a reasonable cost.  There were several "pair
of 813s in Grounded Grid" circuits published back then, followed by the
'pair of 572Bs in GG' designs.
BTW - they work just fine today if one can find one of those old
homebrew amplifiers - but they are usually large and built on rack mount
chassis, some used plug-in coils while others used a PI-network output
circuit.  Yes, they had to be tuned to resonance and loaded to the
correct plate current draw, but that is not much different than
adjusting a manual ATU in today's world - we just moved the tuning
mechanism outside the amplifier.

"No Tune" amplifiers are not new - Centronics had one available back in
the 1960s.

No, but a popular mobile amp that ran 600 watts were selling for
considerably less.  I used a Henry 2K-2 for years until it good too damned
heavy for this old man to horse around!  I now have an Ameritron AL-811H
Much lighter and 500 watts is very adequate.  Will run more, but why do it
as the 811A's I have will last a long time at 500 watts CW.

Solid state would be nice....BUT.  Hard to by on a retirement fixed income.

Just a couple of things:

1) Unless all of your antennas are very well matched you'll need a tuner. An
autotuner for 1200w is relatively expensive. So 'no tune' is not exactly true.

2) It doesn't appear to include QSK; the band decoder is also extra.

3) It says "1200 watts of clean SSB output". I suggest this means 1000w on CW and
600w RTTY.

Because of 1 & 2 it's not so cheap.

RE: OT: new SS amps

Jim-168
Well the ALS 600 I had did not put out 600 on all bands. It was especially
down on 80 meters more like 425 to 450 watts although plenty of power. I
understand this is typical with the 600 so it makes me wonder if this amp
would truly put out 1200 on all bands or even miss 1000 on some bands.

Kind of a bummer, no QSK, band decoder or as you see as that added extra in
the foreign amps, 6 meters.

I bought my 572Bs about ten years ago, 10USD for each one. After 50000+ QSOs, I replaced it about 3 years ago. Not bad for 30USD investment. I was heard the new 572B is not as good as ten
years ago, that is only because the dealer (in US?) need more cheaper 572Bs.

All the best!

In reply to this post by Vic K2VCO

With 8 x MRF150 the ALS-1300 has the same transistor component
at a Quadra ... and probably the same power output.  What is
lacking is six meters, the tuner and QSK.  

As far as the "band decoder" ... ALS-1300 will be +12V to select
band (all on one RJ-45) vs. Yaesu format BCD for the Quadra (only
works with Yaesu radios).  I can't see much difference there as
one could do the job with a W9XT BCD-10 for $20.  

QSK probably just needs faster relays ... so it really boils down
to is six meters and the tuner worth the extra $1000.

RE: OT: new SS amps

Bruce McLaughlin-2
In reply to this post by WILLIS COOKE
It's funny how experiences can differ.  A couple years ago I decided to
refurbish my old Heathkit SB-200.  Included in the project was a set of new
tubes to replace the original tubes from 1972.  I purchased a pair of
Svetlana 572Bs from RF parts.  One of them burned out its filament after it
was turned on for about the fourth or fifth time.  I have never had a tube
do that before.  RF parts exchanged them for a set of Taylor tubes which
have worked fine for the past couple of years.  I guess all this means is
that when you are buying imported tubes the quality control may leave
something to be desired.  Eimac tubes may cost much more, but except for
some well documented exceptions, they generally appear to be much more
consistent and robust.  Frankly, I would rather pay more for the amplifier
up front with good Eimac tubes instead of being forced into a game of
Russian roulette as to whether the tubes will still be available when
replacements are needed, sometimes a lot sooner than should be the case.

Re: OT: new SS amps

In reply to this post by DOUGLAS ZWIEBEL
I have owned an ALS-600 for the last 5 years and have, for the most
part been quite happy with it. I did an expensive solution to the "no QSK"
problem by purchasing the Ameritron QSK-5; the pair work flawlessly
together with fast, "thump free",  full QSK.
 
My biggest complaint with the '600 is the really cheap-o, Mickey Mouse,
decal for the front panel labling. The thing has a tendancy to start peeling
along the edges of the panel, bulging out, and basicly looking like hell. I
find a carefull application of something like Bondini II between the decal
and the panel works fairly well to re-attach it.
 
In the case of the QSK-5...it is VERY sensitive to high SWR (I still haven't
determined what HIGH actually is). Anyway, when HIGH is exceded, the
 two parallel 12V bulbs, used to protect the pin diodes, go bye bye and
need to be replaced. After you have ordered the replacements from Ameritron
you have to open up the QSK-5, unsolder the old bulbs and solder in the
new ones. This is certainly not difficult, just simply annoying...I've had to do
this 3 or 4 times and finally ordered a handfull of the little beauties so I'm
prepared. A resetable fuse or socketed bulb would be a real improvement
to the device.
 
As far as Elecraft amps..it seems to me that high power amplifires are basically
a comodity item, bringing out another amp simply dilutes the market,
unless there are compelling features to make it stand out from the crowd. It
will, at best, hold its own. I would hate to see Elecraft embark on a money
losing venture, especially in the current economy.
 
Despite all that I would love to have a KPA-800!

To me, the word "commodity" means it's so simple anyone can do it
well and do it inexpensively. If you really believe high power amps
are a commodity, I invite you to design one, get the bugs out of
the design, put it in production, and get the manufacturing bugs
out if it, then sell it for price that allows you to support it and
stay in business.

If at the end of that process and a few years in business you still
think it's a commodity, I'll buy you a case of your favorite
beverage. It's like I taught my kids -- the other guy's job always
looks easier.

73,

Jim Brown K9YC
