[Amps] Dedicated RF

[Gary K9GS]

Well, my point is that I'd be happy to see some 
experimentation/development in SS amps, instead of another commercial 
amp using hideously expensive tubes.  Let's face it, the days of the 
3CX800 are numbered.  Why introduce a commercial product with expensive 
and, potentially in the near future, hard to get tubes?  Other than a 
handful of ham radio amplifiers, is there any commercial application for 
3CX800s other than replacement parts?

If you're going to introduce a tube amp at least pick some reasonably 
priced tubes.  The Alpha website lists a pair of 3CX800's at $2100.00.  
That's almost 1/3 of the selling cost of this amp.
