Nigel,
I am seeing thr phenomenon I described, but you must right, as I am
taking the output after the amplifier, and that is likely not on the AF
gain pot, so I was probably wrong citing the tap location. I don't have
access to my schematics or a PDF viewer right now.
I tried taking the output before the amplifier, but it wasn't high
enough level for my sound card, and I was troubled by noise on the low
signal. So I moved the tap to after the audio amplifier and that is
where I am seeing the audio pickup from the speakers.
I did buy one of Don's digital out boards, but didn't install it yet.
Someday...

And how exactly is audio from the speaker going to travel BACKWARDS
through the audio amplifier?

If you take the audio directly off the AF gain pot, you will pick up
shack noise through microphonic action of the speaker or headphones.
