[Elecraft] K3 Headphone socket problem

[DK2GZ at aol.com]

Hello
 
the menu parameter SPKR+PH is set = NO
 
When I plug the headphone into the rear socket there is also audio through  
the front socket, but only if I plug in a second headphone also into the 
rear  socket.
 
If I only plug it into the front socket there is no audio in the headphone  
and the internal speaker is not muted.
I guess I need a new front socket and how difficult is the replacement?
