R. B.: Did you measure the C to determine this?
*** The course of action was: I visually inspected the bandswitch through
its operation and determined it didn't have any intermittent, flashed or
vaporized contacts. Backed it up with a VOM check.
***Visually inspected the loading cap.
***Since it didn't have enough loading cap capability, I logically
determined the padder was at fault.

That's because the Load-C padder caps usually are in perfect shape
after the bandswitch padder section contacts have evaporated.
***Yes but not in this case. Looking at the cap from the side, the bottom
post had pulled out. If the top post had left, it would have been visible
from the top. Kenwood must have figured these caps were stronger than they
were, there was considerable tension trying to pull the cap apart.
***I replaced this cap with a couple Centralabs and the owner is still using
it.

Evaporated contacts don't wiggle.
***No they don't do they... It's probably more of a tinkle as they hit the
bottom of the cabinet.
