[Amps] SS Amps are expensive...why?

[Bill Steffey]

heard a great loud signal on 20 a few weeks ago,,,, crystal clear ... 
but there was sizzling 10kc down the band....
the scope on the k3 showed it ,  did not appear big, but I could hear it..
moved to the 7800 and it was indeed there ,,,, still sizziling....
it was Italian ...I did not remember what power he was running,,,,
. maybe he was hitting it too hard???
maybe his amp needed another device to get into the linear region ???

I am no engineer...    " but that's just wrong"

""""It looks like you are buying a
board without the LDMOS.
No Control Circuitry
No output filters"""""

not really, that amp has all the stuff, all the filters, the 2 LDMOS rf 
pallet is even all tested and biased up.  The controller is installed. 
You do need to solder some teflon cables. And install some fans and a 
rasberry pi. tough stuff.
