This headphone PCB is just a replacement PCB of the original. A few people asked me about doing one for the transformer board but I don't have one in front of me to replicate, I've only seen a picture in a manual or whatever.

Hello I would like one pleases 
IRT missing board in between. ( 839-0244 )
https://wiki.arcadeotaku.com/images/7/75/Sega_swing_wiring_diagram.jpg
that board is not covered in the swing manual
that board is covered in the aero city manual though.

so. my aero does have the headphone board, but bot the amp, I was told by the seller that it's not needed. worked fine without it. the aero wiring direct connects into it. I'll have to try it out.

Could you measure the bracket that holds the pcb? Mine doesn't have one, I'm going to try to make one.Don’t get it twisted. There’s a connector in the aero city as well.

if you test it out and it ends up working , let us know. take pictures of it and how it's wired up.
I don't have the headphone board or the transformer, however, on an Aero City I do have the harness from the bottom of the cab up to the control panel.
On the bottom of the cab, it's a male 3-pin Mate 'n Lok connector with male pins. On the control panel side it's a 3-pin JST NH connector.
Pinout is the same on both ends:
pin 1 - GND
pin 2 - SPK+ (jamma pin 10)
pin 3 - SPK+ (jamma pin 10)
As the speakers are wired in series, both pin 2 and 3 will show continuity with SPK- too.
Some things to consider, 1) the headphone harness is wired in parallel with the speakers, and 2) the audio coming from the harness is, of course, amplified. What does the underside of the headphone board look like?

Could be fine to modify the original one to add Amp , as this one , 5v and no heating https://fr.aliexpress.com/item/32878308762.html?spm=a2g0o.cart.0.0.18683c00RrMZG3&mp=1

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
