Could we get more info on this possible fix, how much disassembly is
required? Looks like the PA unit must come out?

I think I may have solved this problem. One of the other posts mentions that
the Z-bracket screws are too long and you don't get a tight fit. I changed
the five screws from 5/16" to 3/16" and did notice a better grip between the
bracket and the PA assembly. I have run it all evening and haven't heard a
click or a pop. I even ran the temp up and still nothing. Will it last? I
don't know, but it seems to have fixed it. The guy who suggested this has
submitted it to Elecraft for a change. Good luck and lets hear if any of you
have the same result.
