[R-390] Variable caps in coils

[Jim Temple]

I have one more "gotcha" that I hope the collective knowledge of this group
can answer.

I have found that a source of considerable noise, popping, and static are
broken wafers (the wafer that sits between the rubber grommet and the actual
cap).

The question is:  Do both the cap and the brittle wafer work as a matched
pair?  Is it possible, permissible, to retain the cap and replace the broken
wafer from another cap of a different value?  Are all wafers created equal
(from within the set in these radios)?

Thanks, guys.

Jim
