    Has anyone used AI to aid in repair?

    Can this be fixed.

    Yes, the tube is ‘necked’, meaning someone or something put enough force on the neck board to break the glass neck, letting the vacuum out of the tube. It’s like breaking a light bulb. The tube is trash.

    Dragon's Lair Restoration

    FYI, a 24-hour soak in white vinegar, followed by a scrub with a brass brush will remove rust. Everything can be restored.

    Star Wars vector monitor

    Yup, that’s what a bad flyback looks like in one of these. It’s not common, but when they go, you’ll see clear melt marks in the side. (Often they’ll have a nickel-sized hole melted into the side, lower down). But when you’re rebuilding these, if it isn’t melted, you can generally always...

    These games have survived over 40 yrs. Will they make 40 more?

    People act like CRT’s are evaporating or disappearing. Or they’re fragile things people need to worry about. There’s no reason the CRT in any game today can’t last as long as the original Mullard tubes I have in my ST-70. If you’re only running your games a few hours a week, you aren’t...

    Pots for a Tempest main PCB

    Yep, I still use the 3386's. (And yes, Kapton tape and leg bending is still required. But that's easy.) There are ones out there that are a better fit for the footprint. But they aren't the style I like, as they have the thumbwheels, and are bigger, so they sit higher on the board, and just...

    Super glue as wood hardener

    All very good points. I was just going by how it smelled and acted. It made me want to try to mix the two, just to see what happened, but I didn't have enough CA on hand. But yeah, maybe the CA recombines once the acetone dries up? Dunno. The fact that they don't seem to be very clear...

    Super glue as wood hardener

    In which case it made me wonder at the time if you could make your own. Only because the Varathane is expensive (like ~$20 a bottle, IIRC. And one bottle doesn't cover much if you need to do many parts of a cab. I think I used three bottles total.)

    Super glue as wood hardener

    I've always thought the Varathane wood hardener you can get at Home Depot was actually just a diluted form of super glue (cyanoacrylate). I used two cans of it restoring my Avalanche cab, which is particleboard, and mine was falling apart from moisture damage. It worked well and fully...

    Missile Command Power Questions

    It really shouldn't matter which power supply it has, as they basically do the same thing. As long as the wiring isn't hacked up, it should be fine. Start by inspecting all wiring, and testing all voltages. Also, see this post for how to bring up an unknown-condition Atari game...

    Asteroids wild northern lights halo?!?

    - Try turning the brightness down on the deflection board. You may also need to adjust the contrast to compensate. - If you still see the retrace lines even with the brightness turned down, it's a problem with the Z axis signal, which could be on the deflection board, or the game board. If...

    I need help understanding the operation of the video processing circuits on a pacman upright arcade board

    Use Kester 245 no-clean solder, then clean any remaining flux off with a Qtip and acetone. Or better yet, use Kester organic flux (aka water wash) solder when replacing that many sockets, then just rinse the board under hot water to remove the flux, then stick in front of a fan to dry...

    Sad pictures of arcades 11/04/25

    That's heartbreaking. However as others have said, every metal and electrical part in there has value. I get if it might not be possible, but if it were me, every one of those cabs would get completely stripped, down to every nut, bolt, and bracket.

    What's Wrong with My WG 6100?

    It's one of the transistors on the lower aluminum plate that has the 4 transistors on it. Most likely the 3716 that is furthest away from the tube, under the corner of the deflection board where the LV2000 board is. (Which is the lower left corner of the board, looking at it from the back of...

    G05-801 - G05-802 Adapter Needed

    Cool. Thanks for the data. I don't put much stock into serial numbers, since we know Atari didn't number cabs sequentially. So it's hard to correlate that info. The only other thing I'd question is if all of those cases were actually from the factory with the 12-pin connector. (And weren't...
