Hey guys. I'm wondering if there's anything special about the wiring on the Aero City, since capturing using a GBSControl scaler is giving me sync problems on Aero City and not on my Supergun and Versus City.

The setup is as follows:
board -> JAMMA edge -> cab / supergun
-> JAMMA edge -> THS7374 splitter for 75ohm output -> GBS Control



I have a bunch of Aeros and they all seem to have the same issue, while it is flawless on my Versus and Supergun. Something seems to be affecting the Sync on the Aero, and it happens on MVS, CPS2, and Namco System 12. It is significantly worse on the CPS2. I'm completely stumped!
 
NVM I actually solved the issue with the Aero City. I can get them to sync perfectly now. With the help of a gentleman from FB arcade groups, I found that completely disconnecting the monitor makes it sync correctly. The chassis might be messing with the signal! So the trick is to not tap both sync outputs on the same point.

This is the way I got it to work: I have my GBS sync coming from the LM1881 circuit, and the sync to cab coming from the THS7374 output. FINALLY a working capture from the Aero!!!
