WA2EBY MOSFET amp
 

I came across Mike Dossor's mosfet hf amp in the 3/99 QST and am
interested in using it as part of a mobile psk station. Anyone out
there built this? Specifically, I'm looking for substitutes for the
heatsink which is apparently no longer available and generally any
hints, tips, gotchas... Thanks in advance.
