Amplifier to build

[Julius Fazekas n2wn]

This is another source of more involved amplifier kits
for those who like a challenge. They have been
recommended to me any number of times, although I've
never used them (nor have an interest in the company)

 I just assembled the AN762. It is an easy build, although the directions
are nowhere
Near Elecraft quality. I had to go between the drawings and the schematics
some to figure out what went
Where. The amplifier modules are pretty robust, and well designed. Very good
quality stuff.

I recommend them.

Hi Mike,

The AN762 has sparked my interest too.  I have several low power rigs
besides my K2.

Can the power output be easily adjusted to say 25w, and if condx
warrant, crank it up or down on the fly?  Also, I take it you need to
build a set of low pass filters for every band you plan to operate.

I love to see a picture of yours of it's not too much trouble.  It
looks llike a great project for the Christmas holidays.

73, Paul   -ve1dy-

FWIW. I built one of the CCI amps (don't recall which one at the
moment), and I was not very impressed with the input or output return
loss. I have a plot from my VNA if interested. Distortion was fine, but
the match was terrible.

FWIW on the AN762. I built one about 4-5 year ago and had nothing but trouble with it. Got almost no support from the supplier. Finally gave up on it. A couple of months ago I finally built up the courage to dump it in the trash.
