[Elecraft] K3 Back Panel Phones Jack... my solution...

[Don Wilhelm]

John,

I will try responding in case Tom is not monitoring right now.  That 
adapter wires all the tips together and all the rings together.
Tom's adapter wires the tip of the plug to the tip of one of the jacks, 
and wires the ring of the plug to the TIP of the other jack.
I do not know of any adapter that does what Tom's does.  It allows 
either a mono or stereo plug to be inserted into the jacks with the 
speaker wired only to the tip and the sleeve.  One speaker will carry 
the left channel info and the other speaker will carry the right channel.

73,
