I'm not sure how many hams want a no-tune amp--tuning a tube plate to low Z 
doesn't really bother me that much, in fact I prefer to do it myself, not 
trusting some logic circuit to tune and load for me.  however I know one of 
the great things about the PW-1 is that it follows the icom exciters making 
them 1 kw transceivers which I must admit is pretty nice.   Also, it's 
easier to remote the amp when it's no-tune.   But I think a lot of hams make 
buying decisions based primarily on the purchase cost.   Since they aren't 
transmitting around the clock every day of the year, operating costs aren't 
that much of a consideration.    If I transmitted all the time, a 90% 
efficient s.s. tx would be attractive to me.  So, in other words, I 
understand the broadcast industry moving to s.s. but their reasons mostly do 
not apply to hams, at least for now.   If a s.s. 1.5 kw ham amp or even a 1 
kw ham amp can hit the $3K mark, then things will change.

re the SGC, I did not know about the IMD problem.  Ron, do you know how the 
PW-1 does in that department?  it has a reputation for being a pretty robust 
s.s. amp--i heard the 1 kw pep spec is conservative.
