The 4CX250 amp looks like a CB amplifier Skipp. It certainly can't 
be a very good amp for ham radio.

It takes 1-5 watts of drive, and worse yet has no screen regulation, 
current limiting, or metering.

I certainly hope not many are used on amateur bands!

It looks like a copy of a CB amplifier marketed under the guise of a 
"amateur linear" by a company that sold out-of-band crystals for 
CB radio's in the 70's and early 80's.
