Quoted from PanzerFreak:I just wouldn't buy one with original 5v boards unless all of the light boards have been replaced. All of those games should have exhibited issues by now. I think around September of 2013 JJP switched to 7.5 unbuffered boards, then moved to 7.5 buffered boards and finally to the 2.0 board system that is used in all JJP games today.
Many owners of 7.5 unbuffered and buffered games have never had board issues. Going on over 4 years here with 7.5 unbuffered boards and have never, knock on wood ECLE apron, had an issue.
This really isn’t accurate. 7.5v buffered boards aren’t really any better then 5v buffered boards. The bigger issues come from unbufferecboards whether they be 5v or 7.5v.
