RE: [Elecraft] OT: new SS amps
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: [Elecraft] OT: new SS amps
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!

Re: [Elecraft] 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. 73, Don W3FPR WILLIS COOKE wrote: Sandy, did you ever take a look at what a kilowatt amp cost in 1955?

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 niceBUT.

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.

RE: [Elecraft] OT: new SS amps
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. 73, ...
