Hi guys, new to the site and really green to arcades I use to play growing up as a kid. I know very little and what I do I have taught my self over the last couple of weeks. So with that being said here is my problem. I took out my NBA JAM board and sound board and replaced it with a NBA JAM T.E board and sound board I picked up off ebay this week. Everything went smooth but my only issue is some sound distortion. Sounds like a bad radio channel. Never had the issue before replacing both boards. Thanks
