Forgive my ignorance, but just comparing the input volts/amps to the output
would seem to indicate an efficiency of ~75%, which would indicate class C
operation. How could these be suitable for anything other than CW? Am I
missing something here?

Subject: [Amps] 4Z4RB amplifiers
4Z4RB has a number of SS amp boards for sale on eBay at attractive prices,
but data on them is pretty scant. Nothing of bandwidth, IMD or duty cycle
for example.
Here's one:
http://www.ebay.com/itm/2KW-VERY-HIGH-POWER-2x-LDMOS-BOARD-LINEAR-AMPLIFIER-
/161284955586
and there are many others.
Does anyone have any experience with these? With no data I am pretty leery.
Thanks in advance,
73, Bill W6WRT
