Long ago Ten-Tec made a model 405 amplifier. It could take 5 watts in
and produce 50 watts out. There are also some Tokyo Highpower amps
around that people have bought directly from Japan. You could also
arrange to buy one directly from the company. They technically aren't
legal because the FCC has restrictions on input power, bands and gain to
(unsuccessfully) prevent CB operators from running more than 4 watts
output. Otherwise, there are plans and boards to build a 140 watt amp
that would be quite suitable. I also believe it is possible to make the
KPA100 an external amplifier. I've used a number of these and in my
book if you want 100 watts - buy the KPA100. I built one of the first
and it was a gem.
