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.

Joe, you may be right, but the description of the Revision C mod says, "This 
modification protects the K3's audio amplifier if either speaker output is connected to a 
short circuit or very low impedance load."

Since I've made this mod, I'd like (hope) to know that this protects the audio 
amp.
