[TV MAN]

I think you are right on Arran! I had a 50's AM/FM with that silver mica problem and I sat it in the back. Likely parts. This FM3 sounds so good as compared to other tuners, it would be worth the effort. The sound quality is outstanding! If it drifts again, I'll probably redo the cans. I'm sure that's what was wrong with the disc coil. I could rock it and it would come and go, so probably as you mentioned, poor contact inside the can. I might experiment with the already open can and see what I can accomplish. I'm about to start a thread on my Fisher, and I suspect it has the same problem.
