This one statement makes me a little worried about buying these boards. With all of the technical know how on Pinside and thousands of threads from discussing problems with the original board designs, questioning why they did what they did, I am not likely to buy original designs.

Now Charlie if you provided some explanation of when you do make changes and why it makes it better than the original, that may change my mind. With all of the board repairs I have done on my recent projects, I would rather look at something that fixes the problems rather than put the same back in.

You are probably right.

I am sure anyone who designs circuit boards has stories to tell about all of the failures before they got it to work.

A shout out to all of those board designers (XPin, Rottendog, Alltek, Gulf, Pinball Basement, and everyone else) who keep this hobby going and never give up. Without you, our games would have died years ago! Keep it up!

Of course he wouldn't be selling crap. That is never anyone's intention putting stuff out to sell. What I said was...

Earlier this year I picked up a DE Time Machine with a Gulf Power Supply. Didn't have any displays. I am sure the reason why is that the HV section on that PS was torched. The transistors were cracked along with a few other parts. I put an XPin display in it and the game is fine. What I am saying is that nobody's designs are perfect. The XPin display was a Revision C so it stands to reason that he had discoveries and needed to change things to prevent whatever had happened on previous revisions. Anybody who says their designs are perfect the way they are, I tend to run from. Crap happens.
