[Elecraft] K2 Sudden Loss of Audio

[Roy Morris]

I keep losing audio.  It doesn't happen with any regularity.  I never know when it will happen.  I just changed bands, and the audio went completely out.  I plugged in a set of headphones to first the front headphone jack and then the back jack thinking it was a jack problem.  The headphones were just as deaf as the speaker.  The s meter function remained normal the whole time.  I know if I turn the K2 off, the audio will return when I turn it back on.  I believe Wayne said something about looking somewhere at the AUX BUS circuit, but I don't remember where.  I believe he said the NE602 is a hefty chip and probably isn't the problem.  I lost his response on this.  Can anyone help?  Thanks  Roy Morris  W4WFB
