Weche 'Ok Baby' Arcade Cabinet Restoration

does this chassis require an isolation transformer and are you using one?
Click to expand...

The chassis is a generic one from China, as far as I can tell. Can't find any info online by searching model numbers. The cab did not have a isolation transformer when it arrived. It also didn't have a ground wire on the incoming power cord. It had a janky-looking wiring setup, that could have been daisy-chained off another cab (had an outlet on the back in addition to the power cable to plug in).

The monitor had been running fine for weeks prior. I'm going to pull it out and see if something got bumped or snapped when I reoriented the cab. I opened a different thread for troubleshooting the monitor - https://www.arcade-projects.com/threads/ok-baby-no-picture-and-chassis-is-a-mystery.27476/

[Edit: Chassis has been identified as a Yatta Model 988]

Hey everyone! Happy Thanksgiving!

Life intervened for a bit on this project, but I wanted to come back and provide an update.

First things first, with the help of some folks in the monitor support thread, I got the picture fixed on the chassis with a judicious replacement of a capacitor controlling the horizontal width.

Control Panel - I ordered a replacement CPO from https://arcadeartrepro.com/product/weche-ok-baby-cpo/ and I can say that I am happy with the delivered product. I will say be prepared to wait awhile, it took about 2 weeks before my order processed. However, shipping was great and it even came with a little card thing to smooth the CPO. I believe this is a small shop and customer support was great when I reached out.

After a nervewracking 15 minutes I had the overlay on, with a pretty good alignment.

I added a Noctua fan to the cab for some air flow and replaced the marquee light with a couple of led strips from amazon. They run on 12v so I was able to use power from the jamma loom I bought to hook it all in.

And with that... I'm done!!!
Really glad with how things turned out and I do indeed love this cab (and I will find a dedicated pcb that suits it soon, I promise). I almost got a 2nd one at auction recently, but didn't win.

I wanted to thank everyone here for following along and providing good advice on getting this thing up and running. I've learned a lot and my passion for this hobby is only growing.

P.S. One last pic of the next generation having a turn!

This came out great! I've always admired these little cabs and yours came out awesome!
 
I've worked on restoring a few Jaleco Pony mk4 (the cab the OK Baby is a clone of) and it could have been a nice cab if the plastic it's made of did not become that fragile. It quickly became a nightmare to work on, as all those screw inserts broke one after the other. I don't expect the ones supporting the weight of the front glass to survive very long.

Definitely not a cab I'd let children play with.

Alright, where did we leave off? Painting...

Trigger Warning: the following pictures contain material that may make you uncomfortable. If you do not wish to see subpar prepping, small imperfections, or things you would do better please avoid this post.
At this point I was/am still terrified of breaking anymore of the plastic on this machine so I took an approach of limited risk. I partially dissassembled the unit and only sanded the worst spots to get off gunk or smooth down gouges that I felt I could do safely.

I mentioned before that I had found videos claiming this spray paint did not require sanding. I did a test on the front panel to see how it looked.

Satisfied with this I removed the top/front of the cab, the side rubbers? and then taped up the rest before painting.

Hi.
Could you tell me what brand and type of spray paint you used to paint it, without needing a primer?
 
Just got an OK Baby (from Yubiparts on here!). Very excited to fix it up. I think I am going to sand and/or Novus 3-2-1 it a bit before I spray paint it down. I am actually writing about it for the site I co-own. Excited to use this and other threads as a jumping off point.

An interesting point is that the cabinet seems to be entirely ABS which is novel and retrobriting that entire thing seems like a fools errand. It also seems to have some kind of clearcoat on it. I am probably gonna bring it to an auto shop and use their spray booth. Debating keeping it stock gray or going project mode with it.

My unit has a crack along the edge of the control panel (common stress point) so I am wondering if JB Weld or Plastic Welding with stainless would be stronger for reinforcing that. I also need to replace the PSU and my understanding is the Meanwells are reliable (my experience with those has been fairly positive with LED Drivers).

I also have no idea what tube is in there. One of the handles that helps pull the monitor out collapsed and crumbled so I am looking for a replacement. I would love to get a trisync in there eventually but that's down the line.

You should start a thread in this section. Id love to see your OK Baby progress on this rather than remembering to go to yours. Best of luck

I wasn't aware of Novus products before I did this resto, curious if Novus 3 would be sufficient to prep for a repaint. Good luck with your resto!

For the chassis look at my other thread to fix a monitor issue. I want to say it is a clone of the nanao chassis.

Oh yeah I’m going to. Also going to be documenting it on Aftermath.site. I just thought I’d give credit where credit is due.

I am going to test it out. Again I’d do vapor retro brite but that’s not logistically possible. Probably will do some wet sanding too.

Thank you. I’ll look into your other thread, we may not have the same chassis, I thought these were dual sync generally? Was hoping to get it to do 31 as well down the line.

Most of the ones that made it to the states don't have original anything, hard--candy website does say it was originally dual sync monitor:
