I apologize if I sent this out a month ago and might be repeating it. 
Memory is one of the first things to go with age right? Damn, need a 
daily dose of RF....
Polyfet has been making good gold-metallized DMOS transistors for 
VHF/UHF power since 1985. The web site has some good information, 
including schematics of typical power amplifiers. Take a look. Also 
the articles and presentations are interesting, one has typical 
stabilization circuits for MOSFET power amplifiers, presented by S. 
K. Leong at the 1997 IEEE/MTT conference. They aren't bipolar 
amplifiers, so the principles are different (BJT vs MOSFET gain and 
freq response).
