Title: Galaxian = WG K4500 ?
Post by: Level42 on December 22, 2006, 06:02:51 pm

Can somebody please confirm that this (http://forum.arcadecontrols.com/index.php?topic=61246.msg608069#msg608069  scroll down to msg 17 or so) is a WG K4500 monitor ?

I think I identified it with the help of Bob Robert's site but I'm not 100% sure.

I need to order a capkit for this.

Thanks !

Thanks !

Does anybody have a capkit list for this one ? The biggest problem I have with this monitor is convergence. I doubt that a capkit will help with that, or am I wrong ?
The second problem is that the picture is quite dim when it's operated with the original dark plexi bezel. I think a capkit might help with that.

convergence problems are usually down to a maladjusted yoke-maybe boosting the colours and contrast/brightness will give you a better picture with the plexi

Galaxian was manufactured with at least 4 different make/model monitors during the production run.

I think I will call in the help of my uncle who is a very experienced radio and TV repair man, and has worked with TV's from that age (and IN that age :) )  I've got the manual, and there are some instructions about adjusting the convergence, but the one thing I know about it is that you can REALLY mess things up quite easily.

I think it might not be the yoke in this case, there's a huge PCB around the neck of the tube with lots of pots to adjust....or is that the yoke adjustment ?

Ken, indeed I've seen several monitors mentioned like the G02 and some Electrohome. I'm pretty sure this one is a WG K4500 because of the typical big PCB on the neck, and the seperate PCB with lots of pots. From the photo's what do you think ?

My Galaxian is a very early one. Serial no. 0815. I've seen a serial number mentione on ggdb.com well into the 24.000 so this is probably one of the first serie. This is confirmed by the very old software version (bonus ships on very low scores, NAMCO label on-screen while Midway PCB) and the black T-molding and white joystick ball as seen on various flyers.

I hope I can fix the original monitor. It would be great to keep it as original as possible and I think the tube is pretty decent still...shouldn't a capkit also fix the dimness ? It is mentioned as a reason for capkitting.

I always feel the need to clean things up when I look at a dusty monitor like this. Is there a need to do it and also what's the best way ? Compressed air ?
