Ce modèle de bornes dispose en effet (comme sur certaines SNK) de 2 sorties audio où l'on pouvait brancher son casque ou un haut-parleur.

Ok, so I finally dusted off this repro board to see how to set things up on my Aero City. I thought there was going to be more to it, but if you just want mono audio it is plug and play. This all may already be well understood by others, but in case not, thought I would post my notes here to save you the time.
Repro Sega 839-0158 has two 3-pin JST connectors for inputs
Speaker - for speaker level signal, which will be filtered by the capacitor and resistor in series for a safe headphone level output
Headphone - for headphone level signal
The default Aero City 36-pin harness has two connectors spliced for audio output
4-pin connector for speakers
3-pin JST that @nem details the pinout above, and is run to the CP see @opt2not pic above
If you just want this to work...
Unplug the 4-pin connector for the speakers
Plug in the 3-pin JST that is in the CP into the "speaker" connector of the Sega 839-0158
It works, and there is no need for the (optional) transformer board. But you would likely want headphones that can control volume, or a pot wired into the signal lines. You could also feed this board a stereo signal if desired as well via the 3-pin JST.
