Hold on, so you worked on an amp, for a known CB'er, for what? Listening? You don't need an amp for listening.
My point is, you are contributing to the problem of the "Kilowatt kickers" on CB, who splatter on our bands oft times. I mean, I guess if money is that tight, but, hey. I'm not in your shoes.
I do know I would have not worked on the equipment.
