To sell to us they don't need certification.  Of course they'd sell a 
lot more with certification and dealers which would push the price up a 
notch.

I'd rather have a true QRO SS amp that'd run the legal limit on any mode 
and stay cool.  That'd mean about 2 to 2.5 KW PEP capability and being 
SS they'd have to be computer controlled to stay legal.

As fat as I see, a true SS QRO amp will still cost an arm and a leg.  
Maybe I'm wrong.  Theoretically they should be able to build a "clean" 
SS amp with IM figures in the 40+ db range for well less than the cost 
of tube amps of the same power within a couple of years.  I really liked 
the Tokyo Hi-Power amps.
