Wells-Gardner K7302 19inch came disassembled.. Is it worth it?

[MagicianLord77]

Hi Guys,

I've got this chassis + monitor combo from a Pinball 2000 machine, when taken out from the pinball cabinet it was all loose and falling apart. I mean chassis half-disconnected, yoke and convergence rings were loose, very loose . The pinball has an LCD monitor now so it doesn't need this monitor.

Now I'm checking the items I have and trying to think about the possibilities, I'd like to make this monitor work to have it as a test monitor or to repair another cabinet or whatever. So, here are the items:

The tube is a Samsung 5108B22 and it has burn marks of "pocket gal". I know that the WG chassis is the original Pin2000 one, but does somebody know if this tube could be the one that came with the chassis? I guess it was swapped?

The questions are:

- Do you think this chassis + monitor combination would work? (don't even know if it was powered on in the past)
- Can I try assembling everything and powering on the chassis to see what happens?
- If it powers on, how hard would be to get the yoke and convergence rings aligned for a decent picture?, do you think it would be worth the effort?

Thanks

I have a k7302 in my Ms. PacMan / Galaga cocktail and it has a Chunghwa ( A48AGY13X86 ) tube.

I'd say its worth a shot, it shouldnt be that hard to get the yoke and convergence rings on and aligned.

Thank you.
Mains voltage over here is 220v, the monitor needs 110v, can I use a regular step-down transformer do I need to get a special "Isolation transformer" for hooking up the monitor? or maybe the step-down transformer works as a isolation transformer too?

I've got one that looks like this, input:220v, output:110v, 100w:

This is most certainly a chassis swap--that tube is way too old to match the chassis. The chassis is a Korean-made Tovis--commonly found in Happ Vision Pro monitors sold around the 2005-2009 era. (The last 19 inch monitors that Happ sold.) The chassis is good and can work as a "universal chassis".

Unfortunately that TV tube looks cooked. Probably high hours and lots of burn-in. I wouldn't bother trying to get it going again unless 19 inch CRTs are hard to find in your area. You would be better off finding a new donor 19" CRT TV.

Do you know if the monitor was working when it was taken out of service? It's possible the chassis could be dead if it was replaced with an LCD. At the very least, these need cap kits if it still has the original caps.

Thank you for the info. I can tell that the chassis is the original chassis of the Pin2000 machine, in this case a WG K7302 (manufactured in 1999). So if it can work as a universal chassis, that's good news . You say the tube could maybe be replaced with the tube of a 19'' TV?
I don't have info about the previous story of the machine,.. don't know what died first, but it seems like at some point of time, somebody replaced the tube it had for that old samsung tube. But anyways, I'm willing to someday try to see what happens if I connect everything, the tube is naked at the moment, I would have to mount the yoke, the rings, connect the chassis. Do I need an isolation transformer for this?

No isolation needed for this particular chassis.
