[Elecraft] K3: Headphone Jack hardware?

[Martin Schmiedel]

Elecrafters,

i think the headphone jack on my K3 #2878 is failing. Audio drops out 
now and then, but returns when i plug in a headphone.
When I set menu item SPKRS & PHONE YES I have no drop outs.

There is no part number for the headphone jack in the assembly manual. 
IIRC the front pcb came with the jack already installed.

Any hint how to try a repair prior to fire up the soldering iron is 
highly welcome.
What to do if a repair fails?


Thanks,
Martin
