You do! Tokyo High Power have one of these based on ARF 1500 transistors.
They have a Vds of 600V so that they can operate on mains voltage-rectified
and filtered.
Now, Microsemi market the ARF 1501A with a Vds of 1200V.these can handle a
mains of 240VAC!
And since you have anyway transformers at the input and the output, you can
build an amplifier without a heavy power supply. Worth thinking about!!!

But what is the price and where do I get them? I still wonder why we aren't
seeing them in amps on the market.
