**  I've seen a Motorola 1200w HF design using two 50V FETs that go for 
$800 a pair.  Efficiency is c. 45% on 10m  Terry Gaiser, W6RU, told me 
that modern broadcast stations use banks of 70vdc   p-p FET amp modules 
which produce 300W each and feed a combiner to get more suds  The 
advantage of transistors for a 50kW BC station is that there's plenty of 
surplus heat for an indoor pool and spa in Minnesota in January.
