Well, I see it is time for Tom to blow smoke and duck the issues AGAIN
claiming that no one else (besides himself) knows anything.
First of all, apparently Tom's comprehension of the English language is
lacking. You will notice that I said a friend of mine owned the amplifier,
NOT me. Is Tom calling me a liar?
My friend is an Old Timer who is an excellent technician and knows of what he
speaks.

My friend does not operate 160 meters.

Tom, only a person as insecure as yourself would accuse someone of using your
AL-80A on CB radio. That is the SILLIEST thing I have ever heard.

I wonder why the anode always had a dull red glow to it even when idling?

NOT nonsense Tom. When he changed it, the anode lost the red glow and ran
much cooler, and the power output went up. Maybe your name is really Albert
Rauch?

The bottom line is Tom, are you calling me a liar? You call many others on
this list a liar.
What was the reason you were removed from the list previously Tom?
