[Amps] Henry Radio

The mention, a few weeks ago,  of the possibility that the Chinese might 
quit 3-500 production and the news that Henry is getting out of tube amp 
production are interesting.

When I heard the 3-500 news I began to wonder who besides hams, still uses 
tubes for relatively low power RF generation at HF frequencies, as it 
appears that broadcasters are moving to s.s. rigs.   I would not be 
surprised if most users of commercial equipment go solid state before too 
long; many have already done so.  I doubt if the ham market alone, is large 
enough to keep low power RF tube (< 5 KW) production going.   Hopefully 
there are users I'm not aware of.
