Alan, Johan and group,

Since experimenting on LF I have discovered the joys of Class E,
many thanks to Alan.  My first 100W TX used an IRF-640 as
suggested on Alan's web page.  A dozen of them could be had for about $10
in 2003.  Unfortunately, they are have gone up quite a bit since then,
although much cheaper than a 6146!   There seems to be a new generation
of hexfet such as the IRFP260 and perhaps it might be possible to use this
in a 12volt 100w amp.  Unfortunately, many  640's came to an untimely
demise in my unsuccessful attempts to get 100 watts with a 12 V supply.
