Dave -

When I referred to the "base" in my previous post, I meant the
microphone's own swivel base (that part of the actual microphone  which
contains the switch, the female connector and the threads for a mic
stand).  When looking at the front of the mic, the wiring legend is on
the right side of the swivel base.  At least it is on all the 664's that
I have ever seen.

The legend reads as follows:
IMPEDANCE CHANGES ARE MADE
ON CORD PLUG.
PLUG SHELL AND NO.1 CONTACT
ARE GROUNDED.
CONTACT NO.2 HIZ.
CONTACTS NO. 4 AND 4 150 OHMS.

Floyd says he has seen one or more without this message and apparently
you have too - Its all news to me.

73,
