Bob,
The problem with the K2 headphone jack has nothing to do with neither
mono or stereo nor with the contacts. There is a built-in independent
switch at the back of the jack body whose activating arm breaks and the
the path to the speaker remains open after the headphone plug is
removed. I have done postmortem disassembly of several of those jacks
and find the same fault with all of them - the switch activating arm in
the jack is a plastic lever and seems brittle to me.
That being said, the headphone jack in my K2 and many many others I know
of has not failed. Yes, the failure percentage is higher than one might
expect, but not all of them fail. Now, if the jack manufacturer would
just use a less brittle material for that activating arm, the entire
problem would be solved.

Is that rear panel mic jack a true
tip-ring-sleeve jack or a simple mono jack?
If simple mono, I'd be uncomfortable
putting a stereo plug into it. Too many
folks have had trouble with the K2's
headset jack. I'm a bit leery of small
jacks in general due to the small leaf
springs in them.
