Just noticing the original idc connector, what appears to be original caps except for one, same for pots, and the corrosion on the rom legs, for starters. From what i’ve Read all this stuff is swapped out in the normal course of fixing sound issues.

This is totally not true! I bought one from Marco 2 weeks ago. In fact somebody goofed in shipping. When it arrived there was a 2nd one on top of the first. Not realizing but wondering why it was so thick, I pushed it into the socket. Then I realized the legs on the 2nd where pinching it to the first. Pryed it off. So I have a spare. If you want it or Marco doesn’t have anymore let me know. But they are still available and not obsolete unless i just got lucky. But still showing in stock

I understand what you are saying. Just trying to help a brother out here. Personally i could care less where they came from so long as they work since parts for these I would imagine get harder and harder to find as years pass. I mean these Xenon machines are like 40 years old. Heck I’m an old perverted fart at 62 that bought a pos Xenon and made it like new for 2 reasons only. One I like the artwork and two, I read somebody said: “Xenon has the best ass in pinball” You cant go wrong with that! Lol

They could be. Just you know you could simply send the board to jj44114 who has responded in this thread. he can rebuild the whole thing and have it back to you in a week.
