[Elecraft] Speakers audio is gone

[Mel Farrer]

Sounds like you have the same failure I do.  Take the cover off and look for the DSP PCB and on the upper left side top is U1.  Mine did not heat up or draw excessive current but was told that it might smoke smell bad and be hot to the touch.   I think your U1 the audio amp is the culprit.  I ordered the AF protection PCB assembly and a new IC from Elecraft.  Not expensive but a bear to replace the SMD IC.  Good luck

Hello

Since today, my K3 is not producing audio on the internal speaker or via an external speaker connected to the rear speaker socket
Audio is fine in my headest via the front or the rear connector

Time to time I can see HI CURR on the display. I must power off and on the eliminate it

Any idea?

Thanks
