[Elecraft] External speakers for K3 - A caution

[Joe Planisky]

Wasn't the mod described at http://www.elecraft.com/K3/mods/AF_Output_Mod_Rev_C.pdf 
  intended to prevent the IC failure if a mono plug was used?  Did it  
not work as well as expected?  Or is the firmware detection just "belt  
and suspenders" protection in case someone didn't do the hardware mod?
