** 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.
