[Elecraft] K3s Hearing low level rear speaker audio with SPKR+PH no and low AF set

[Nr4c]

This has only been a problem with my K3S, my K3 doesn't exhibit this anomaly. 

I frequently operate after wife goes to bed and I want the speakers OFF. but the left one never really is OFF. Only much reduced output.

This morning I pulled out every connection on my K3s and even unconnected the ground.  Nothing changes.  Even with the antenna not connected, you can hear white noise, primarily out of the left channel.  The level on the right channel is just not as pronounced.  Again, the CONFIG AF level is low and if I turn up the AF gain even half way, I can hear receiver output.  Something is not right here.
