[ARC5] Reviving squealing "command" receivers (re-capping)

[Jack Antonio]

When checking the multi-section caps for leakage, also
check for leakage between each section, as well as
each section to common.

Have a BC-946 that would increase its gain as it warmed
up, along with the sensitivity control having less and less effect.

Turns out one of the 3 section caps, each section checked OK
by itself, but there was considerable leakage between two of
the sections, which increased as the set warmed up.
