[SML] Testing integrity of mic cables....

[Dan Sheehan]

possible that cable checks out OK on the continuity test,
but connector fails to make good contact to the equipment,
seen this with old and/or cheap connectors (females get sloppy).

also, Pin 1 should be cable shield  (or signal ground)  and should
*not* connect to connector shell,
continuity tester might not check for this and if there is a spurious
shell connection (=equipment chassis)
that could lead to a hum or buzz
