The K3/K3S Line Out already has isolation transformers internal to the
K3. I do not understand any need to put additional transformers in the
audio path(s).
What happens if you cable to LINE OUT signals to a computer soundcard
(with both left and right channels - some only are one channel if the
input is set for MIC)? You should hear the main RX in the left channel
and the SubRX in the right.
Your external transformers/cabling raises the question of "is it the K3S
or is it your external devices that are causing the problem".
Time to strip everything down to the essentials and begin to determine
where the "failure" is occurring. Test one thing at a time.

My K3s arrived over the weekend and I have been setting it up. I am using
the rear Audio jacks to drive either headphones, or the Line out to drive
an amplifier and two speakers in the stereo mode.
The headphone jack has stereo output ok. But the line out only has right
channel audio. Left channel has nothing but a low hum.
I am testing them one at a time, using the same cable. So it is not a case
of a bad cable. The plug inserts to the same depth in both the headphone
and line out jacks, so I believe the plug is properly inserted,
I have been through both the Main Menu and Config menus, item by item. I
see nothing that would give the option to turn off the left channel of the
line out.
