[Elecraft] K2 no audio output on Part I Test

[Mario Bouchard]

Hey guys,

I'v started my part I test on my K2 S/N 007168, all is good except for the Audio Amplifier and Tone Generator Test section.

I hear nothing from the headphone jack, I've tried a couple of sets of head phones which works on other audio equipment, the headphones are in working condition.

I don't have a clue where to start looking except that I've looked closely at the board for bad soldering, if U9 was the right chip and installed properly and all that is good.

Thanks,
