Using a meter it's still...

I've just fully recapped a Sanyo 20EZ and replaced all the pots and it looks so much better than it did but I've noticed what looks like a purity issue in the bottom right corner. The first picture of Mario is what he looks like in bottom left, top left and top right corner but in the bottom...

For some reason my DK cabinet has had the wood support at the back removed. Could someone that owns this cabinet please tell me the size and thickness of the shelf and the two smaller strips that join it to the cabinet. I've attached someone elses picture showing what part I mean.

I've just installed a Mario Bros harness that I bought from ebay as the original was mostly missing / hacked up (as it was converted to something else). The auction said it was complete / unhacked but of course that is not the case, both control panel harnesses are wrong. I am starting to think...

I'm restoring a Mario Bros widebody that was in a pretty sorry state, but it's slowly coming together. The part above the back door with the handles was obviously missing or too badly damaged that the last owner made up a new one. They did a pretty good job but they didn't bother adding the...

I am restoring a Mario Bros widebody that was missing the power supply along with a bunch of other parts. Anyway I managed to pick up a PP-7A power supply but looking at the manual it originally had a PP-7B. Is it possible to fit an A? and if so do I need to change anything?

Very rare early Japanese Nintendo Donkey Kong 4 stack pcb, this even predates the Radar Scope conversions. I think these were most likely used for location testing as so few have been found but I don't know for sure. It's the early code with ladder cheat, long score names, levels in a different...

I've not seen this before so hoping someone could fill me in why this is happening. I've got a Hyper Sports pcb where the clocks E and Q aren't making it to the top pcb (konami-1 cpu), at first I thought the 504 custom was going to be bad, but that's not the case. The schematics are chopped up...
