Jim,
Thank you, I had read that part in the manual after I posted my question.? I'll see what I can find out.? Been a ham since 1986, but just now starting to learn how things work so it may take me a while to figure it out, but I am all in.
Tony,
There is a good chance the AC3 needs rebuilt.? Thank you for the suggestion.
Steve,
I hope it isn't a tube, but if it is, which one(s) could be suspect?
Thank you all,
Cowan
