thanks to arcadeTV we have a optimized Version with THS 3714 for NeoGeo AES

-cut left side of the three 6,8k resistors for input rgb input of ths amplifier

-cut the left side of the three 75 ohm resistors for output to the din 8.1

-cut BF for sync output to the din 8.1

the perfect voltage divider values for bypass PCB :

R1,R2,R3=7,51k

R4,R5,R6=2,29k

@ AES 3-5 Mainboard Pin 3 Comp Video and Pin 7 C-Sync are the same on both you will get Comp. Video.

After the modification its is neogeo conform Pin3 comp. Video and Pin 7 C-Sync comming from the THS RGB Bypass PCB

For some help of solder side

cable wiring
