If you're using the IPAC instead of the JPAC....GET UTIMARC'S VIDEO BRIGHTNER!!! I ordered mine a couple of months ago and just got around to installing it. WOW what a difference. All the games are as bright as the original PCB's, even through the smoked glass I have on my cab!
BTW the JPAC already has the brightner circuit
Get one NOW!!!
