Id say that the huge majority of illegal power stations are using over the 
counter or homebrew amps on SSB/CW.  A pair of 3CPX1500A7's, 3CX3000A7, 
YC-156, and up, plus big Russian tubes seem to be the weapons of choice 
these days.  I hear many on SSB bragging about their amps year after year.

AM is a miniscule minority of HF operations and a miniscule minority of them 
are running big amps. The battle over the FCC 1500W PEP AM rule still rages 
with many openly defying it.
