[Elecraft] Speaker problem

[Tom Zeltwanger]

Just got K2 5848 complete. Everything looks good except the speakers (int or
ext) do not work. Headphones work great. I double-checked the wiring, and I have
not reversed the speaker wires. 

When I removed the speaker connector, I noticed that there is only about 0.12
volts at P5 (audio) connector on the control board, whether I have the headphone
plugged-in or not, and regardless of volume setting. Makes me think I have a bad
headphone jack switch. I have heard about these going bad. Is is common to see
bad ones from the factory? Or should I be looking for something else?

Thanks and 73,
