FETs like the MRF173 (or similar) have certain advantages. They also
have several disadvantages... one is cost! Franks proposed design
already looks to have a hefty price tag as described.


That's because I don't make cheap, disposable crap. Never have, never
will. But the use of FET's is at the discretion of the builder. The
amp can be built with either FET's or bipolars. No other modifications
are necessary, just a variation in the initial alignment.
