Hello Tom,
In the CQWW cw contest I operated with K9VV as VP2VVV with K2/100 and
wire antenna. On Saturday afternoon while Fred was operating, I suddenly
could hear the K2 receiver even though Fred was using a headset. We
changed headsets and that did not mute the speaker. I vaguely remember
I am on my 3rd jack. I read a suggestion that overheating during
soldering weakens the jack so I was extra careful this time. But I
recently saw a new, profesionally-built K2 that had a broken jack. I
think this problem is more common than was thought.

I wonder how many headphone jack failures are the result of hitting the
headphone plug when the AF Gain control is rotated - the two are quite
close, and yes that jack will not tolerate a lot of lateral motion before
failing.
I just though of a 'cure', wire up a short extension with flexible wire
Could the headphone jack be remote? Could a jack be mounted to the back
panel and wired to the headphone jack pads on the circuit board?
That would open up the possibility of using some more robust open frame
switchcraft shorting jacks.

Kieth,
Certainly one could mount a headphone jack on the back panel - right next
to the extenal speaker jack, but if you want to wire in the resistors and
capacitors and still have the ability to use either a mono or stereo jack,
then the switch that removes the speaker cannot be the normal type
