There is a lot more to the Pinrepair guides than just board mods, they are affectionately known as the Bible for a good reason. I doubt there would be anyone here that hasn't gained some sort of benefit from the guides whether it be them directly solving an issue using the guides or having someone else fix their machine thanks to knowledge gained from the guides.
AJ - let me know if would like to know where you might be able to find a copy of them.
