[Elecraft] New K3 - No TX Audio

[Brad Pioveson W9FX]

One of the three new K3's we purchased for use at our state RACES
station has no TX audio.  All three were unpacked today, and, the first one
to see the light of day (and, an antenna) doesn't know it has a mic attached
to it.  The PTT works, there's just no audio at all into the rig.  Nothing 
is heard via
the monitor, no ALC action, nada.  The transmitter is working as it
generates 100W of CW.  The ops are reporting that they simply have no TX 
audio.

The other two K3's worked normally when hosed up to the same mic.

I've had the ops walk thru the quick set-up chart, checking the CMP/ALC and 
mic gain
settings a couple of times with the same result each time.

I'm not with the radios, so, having to do some coaching from the sidelines.

Suggestions?
