Elecraft Linear Amp

[k1tl]

Does anyone know if the two linear amplifiers that were shown on the Dayton pictures will cover six meters??

I hope so as I was thinking of purchasing a Tokyo Hy-Power next year but would rather stay with a good ole U S of A company since the boyz at Elecraft know what they are doing for sure ! !

According the designer, they WILL.

Another good choice for a medium-power 6M solid-state amp is the TE Systems
0552G, made in USA, a very robust unit that will put out 400W (1:15) into a 50
ohm load. It runs cool without a fan at CW/SSB duty cycles, and will handle
key-down carrier modes with the addition of a fan on top of the heatsink. Love
mine...

For those with no familiarity with TE Systems, I gather that they do a lot of
military contracts and do the ham stuff as kind of a sideline. (Somebody
correct me if I'm wrong.) They don't advertise, they have no website, and
vendors purporting to be distributors for them typically have no actual stock,
so you might as well order direct from TE. Their phone number is (310)
478.0591.

The chances of finding a used for sale on the ham market are slim. People tend
not to sell them once they get them. I looked for a used one for a month
before giving up and ordering a new one.

A good power supply for it is the Astron RS-70M, a big linear job that just
sits there and works. A well-designed and filtered switcher would work fine,
too -- I just have a love of the good old "big iron" types.  :-)

They do advertise in QST every now and then.

I recently picked up a 400W 2M TE Systems amp on eBay for a reasonable
price, so don't give up too quickly.  But they're not common.  I'm not
really happy with high-current low (13.8V) voltage devices, but....

Another feature, not well known nor advertised, is that their (TE Systems)
amps have "active bias".
This greatly improves their linearity and cuts down on local splatter.
Many of the existing solid state amps do not have any sort of stabilized
bias which is why so many of them on 6, 2 and 432 sound so bad.

Here is a weblink to some photos of the TE 0552G AMP
http://www.ad5th.com/0552g.html

and here is the eham 5.0/5.0 review webpage
http://www.eham.net/reviews/detail/3140

and the well known KM0T has one somewhere in the jumble of photos on his
website: http://www.km0t.com/pages/station.htm
