[Elecraft] K3 Speaker Amp Protection

[Don Wilhelm]

But why push the limits?  Using a stereo plug will eliminate the 
possibility of a future failure initiated by the shorted output.  A 
short on the output *does* stress the components even if they can handle it.
Changing to a stereo plug should not be difficult for any ham who can 
solder - or build an adapter if you don't like cutting the headphone cord.
