I forgot to comment on your photos. I see the RF suppression capacitors neatly bunched up on the back of the microphone socket, each with one end going to the terminal nearest to the camera, so this I assume is the common GND / 0V point for those capacitors.

What I don't see is how exactly that common point is connected to 0V / GND - is it connected to the metalwork of the microphone socket body? Is that connected or bolted to the chassis front panel?
