Hi all;

I plan to build an HF power amplifier, output about 80-100W, not critical.
It might look like as those used in popular Yaesu, Kenwood or Icom end PA
stages, i.e. first stage as driver and the second as final amp.

Have you looked at Motorola's website?. There are a good number of
Application Notes there with amps from 10w to Kw's for HF to uWave
described in detail. There is also a company in US that stocks the
'hard to find' bits, and Kits, for them. Sadly I can't find the URL at
the moment.
