Hey! I'm new to the forums here & had some questions about my monitor on my Gyruss cabinet.  It's a Wells Gardner 19K4951 monitor & I was wondering if the Cap kit for the wells gardner 4900 series is what I need for this monitor to recap it?  Also it has burn in & if I wanted to replace the CRT does anyone know what type of computer monitor I should be on the look out for to replace the tube? Any help would be greatly appreciated.

 Thanks in advance.

Yes, that is a 4900. You need to order the 4900 cap kit from Bob Roberts.

You can swap the tube with an old 19" TV. You need to find a TV with a compatible tube, yoke, etc You can cross reference your tube model # with this list here: http://junknet.net/donor-tvs

Cool! Thanks for the info & the link. :D

According to that list there is no perfect TV for a swap with a 4900 (with same YOKE). But, if you find the right size tube and neck socket you could swap the yoke.

I saw that. I guess I'll have to find some 19 in tv's & see if the neck is not too long. Is replacing the yoke pretty simple? I have little experience on CRTs as when I started my TV training with Best Buy/ Geek Squad CRT's were no longer being sold & only saw a few in the field. Wish I would have commandeered the degawser & tube discharger tools they were getting rid of few years back.  ::)

I have never personaly swapped a tube before with a TV but it's my understanding you need same tube geometry/neck length and the right size/kind neck socket. Swapping a Yoke is not too hard but you'll have a lot of adjusting to do afterwards (purity, etc.)

Well, maybe I need to keep my eyes peeled on Craigslist for monitors as I'm currently not in need of a monitor for it. One without the burn in would be a plus. Currently I see a lot of 5 monitors locally,  but from the pictures 3 have bad burn in from Pac Man & the seller only wants to sell them as a whole. :-\  For now I will get a cap kit for the preventive maintenance & hopefully it may also clear the red tint on the bottom of the screen. It seems to clear up after it's on for awhile, so hopefully that may help. When I got it it had diagonal lines going back in forth on the screen, I replaced the power supply & that cleared up that issue. I'm guessing because the suppy being used didn't have the ground from the supplied 120 volts coming in  causing the board to give a staticy signal to the monitor. The supply in it was not the original & was 2 supplys, one was a AC voltage converter that went to another supply that outputs the 5, -5, 12 volts with no markings & extra black wires going back & forth between the 2 boards. It was also just dangling by the PCB.

Also, keep your eye out for junk games on Craig's List that are cheap and have 19" monitors. I have gotten many a monitor from buying $50 undesirable games. I'd pull the monitor then give the cab away. :)
