Removing the grounding point near the PCB door on the height adustment leg removed *most* of the interference (the one that has the wire looping into field ground into the PSU), but there's still vertical waves coming from the magnetic(?) ballast at the top of the cabinet. Even after I unplugged...

I've determined that the ballast marquee light in my NAC is generating monitor interference. If it's unplugged the noise is completely gone. Would re-routing the AC wires fix this, or could the ballast be shielded somehow? I'd prefer to keep this original but if it has to be replaced by an LED...

Had a great experience with @ImportantBet , super fast communication and shipping, just overall excellent seller here.

Thanks, was checking if anyone on the forums had one first as this is one of those game that sells more in Japan for some reason. Recent forum posts and eBay is quite a big difference compared to YAJ.

Thanks, looking for a green Japanese board at this time

Oh that's right. Looks like you'd just be missing the demag feature and since those pins are NC it should be safe to leave as is.

I just did this swap of the 400-5198-01Y to a 400-5261Z and the pinouts were identical. However, on this swap that entire 5x3 pin molex, the pinouts are completely different. It looks like you would need to crimp a new one. According to the stock Astro (I don't think the 400-5198-01 model was...

Confirmed that the 400-5261Z is a compatible swap for the 400-5198-01Y, so I assume those other models listed would also work. It also fixed the monitor interference (visual horizontal waves) problem I was having and the 12v issue of juggling 2 PSUs. Changing the transistor at IC3 with a 78L05...

The 400-5198-01Y is interchangeable with the 400-5261? And all the other variants with that same pinout? (400-5198CE-01Z, 400-5198-01X, 400-5261Y as long as they dont have the bundled amp) No hidden gotchas with swapping these?

Comparing the regular Astro City (400-5198) to the NAC manual, it looks like those two outputs are not even wired in the Astro. Since it's not needed to power any other AC parts in the NAC I'll assume it's safe to just terminate those two wires along with the others that were spliced out and it...

I've got an New Astro City with a generic PSU wired into the stock 400-5198-01Y PSU. It's worked fine enough for years, but enough small glitches occurring that it's time to go with just the stock Sega PSU. Have another recapped 400-5261 that's ready to drop in. I'm wondering if anyone knows...

I was just guessing! According to twistedsymphony's reference codes it is a Eight Forces/Zing Zing Zip.

I have a JJ Squawkers conversion that I assume was a Blandia, I'm guessing this would work? I would vote option #1, amazing job on this!
