Hams were running dual 4-1000A's long before CBers and there are plenty of
those and bigger amps on the air today. Some simply want to always be the
loudest and first in a pileup and dont care about laws.
At a "reasonable" 4500V a single 4x1 will easily put out in excess of 1500W
24/7 in CW, SSB and RTTY as long as the air supply is sufficient and the
other components are able to handle that duty.
OTOH, a single 8877 will put out 2500W at a lower voltage.
