[Elecraft] Line out dead

[Merv Schweigert]

Seems I have lost one channel on the line out of my K3.
I have been using it on RTTY for years and suddenly
there is no audio output on one channel of the line out.

Is there a setting I could have changed by accident or
did the line out audio go south?

changed cables etc and there is nothing at the rear jack
line out of the K3 on one channel.
