[Elecraft] K3 Configuration - No mono plugs in the stereo spkr jack!

[eric manning]

DO NOT, repeat NOT, plug a mono plug into the stereo speaker jack on the 
back of your K3.

The manual says that the microprocessor firmware will switch the audio 
to SPKRS 1, which it will.

However, if there are other events queued up for the cpu to process, it 
may take some milliseconds, during which time

the shorted output may blow the audio amp, which is chip U1 of the DSP 
board. {What is the audio output doing on the DSP board instead of the I/O board? - but that's 
another story}

You then get to replace the DSP board - like I did  -  which is 
good fun but  a fair amount of effort. And it costs the company $.
