[AMPS] CB amps on ham bands?

Most of the solid state 2 to 30 MHz ones are actually quite good
as far as harmonics are concerned.

As long as they are not over driven.......

As a precaution it would still be wise to run the output thru a Pi L
type antenna tuner and a low pass filter to clean up any possible 
harmonics - a lot of harmonic content  can be even generated in 
the QRP rig and is not a problem until it is amplified.  

Least thats what the spectrum analyzer says for a Palomar TX-75
and a number of others that I have worked on.

I have seen a lot worse on the air from both commercial and home brew amps 
being improperly tuned, -  over driven, -and poorly designed etc.
