hi I come from a arcade repair background and I been working on a stargate arcade machine and I have a problem. the crt I have in the cabinet requires a negative composite sync signal from the game board for the image on the screen to be stable. while stargate spits out a positive composite sync signal which means the signal will be unstable and jump. so I did some research and find out that 7404 chip can convert a negative signal to a positive signal and since I couldn’t find a board for this purpose and I don’t want to a breadboard I made this in wasynda And just wanted to make sure (sense this is my first designing) this will work and I didn’t miss anything I need to add . Thanks
