[Elecraft] Fwd: Speakers audio is gone

Another mono/stereo speaker comment and question. Fred KE7X covers this topic
well in his reference, as does Elecraft in their Owner's manual...to some
extent. 

Above noted earlier " I have a Radio Shack P/N 274-0374 1/8" Mono Jack to
1/8 Stereo Plug Adapter stuck in the back of my K3. It feeds the mono plug
to my ICOM SP 20." That particular adapter shorts the tip (left speaker
feed) and the ring (next up the plug; right speaker feed) when a monaural
plug is inserted. 

When OHM'd out the sleeve (third up the plug and metal body) sees 8 ohms
between either the tip or ring when connected to the single monaural speaker
(because they're shorted).

Question for those that better understand the Elecraft's audio wiring: Will
shorting the left and right speaker channels cause harm when they see the
same 8 ohm source? 

73, Gary NL7Y

PS: Alternatively I can install a Radio Shack 274-375 dual mono to stereo
adapter, or a simple stereo plug on my mono cord.
