Is there any odd bolt holes or openings cut into the front of the cab?

Whoa, that is a heavy duty relay setup. I see a few orphan plugs hanging out by the coin mechs, best I can tell it was crazy free play mod... maybe a card reading type like Dave and Busters. Where does that skinny black wire go up by the control panel?

Nothing about the power supply section of this cabinet is original Nintendo gear not sure what he box is, maybe take a photo of its internal components.

In before the lock...

Rumor has it, there's a guy in Southern Jaw-Ga.. that dresses like a lady when he picks up machines... Watch out.

And creepy guys named Daniel... Watch out.

No apologies needed! "Fight and Go Right!" Those are some of favs as well!

You should poke around inside the cab, it could be something as simple as a loose connection. Always start with power and make sure you have AC voltage going to the monitor! Then make sure the RGBHV plug is fully seated. Take some photo's inside the cab and report back, probably wells gardner medium resolution in there.

Zero car speakers are shielded and are kind of overkill for most arcade projects. They absolutely will work for the most part but a paper cone driver is fine. In my experience shielded speakers are rarely used unless they are an inch or two from the tube. Try MCM, Parts Express or Arcade boneyard for some. As always eBay is a great source.

Warlords, Battle Zone and Astroids...all are variations of concept art for commercial use.

Do you need one? Sometimes there are not needed.
