[Elecraft] Barebone K2 Amplifier?

[Doug Person]

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.
