[Elecraft] SP3 ISSUE

[Robert 'RC' Conley]

My SP3 arrived today. it is very beautiful and compliments my K3/P3.
However it does not seem to perform properly. If the supplied cable  or
any  stereo cable is fully plugged into the K3 rear speaker jacks and SP3
inputs no audio comes out. However if the cable is loosely plugged in I
have audio. I checked this on the Menu settings of SPKRS and SPKR+PH both.
Am I missing something?
