I bought an unused (1995 era) WG monitor a few weeks ago. It was advertised as a 25" and I wanted it for my Golden Tee. When I called the seller I was on the way to pick it up, I found out it was actually a 27. Although its working status was unknown, and I really needed a 25 incher, it was cheap enough that I still took a chance on it.
I didn't have a chance to mess with it until a day or so ago, but on hooking it to my Jamma cab, I found that it has a beautiful picture.

I sized this up with the Golden Tee, and for as huge a cabinet as it is, I would have had to hack up the sides a bit to make it fit. As it's one of my favorite games, I didn't want to do that. I decided to try to install it in my 25" Jamma Dynamo cab. I made up a new mount and tried putting that bad boy in. I got the mount and front clearance perfect, but it's a super tight squeeze in the back. The cab mounts rub on the degaussing lines around the monitor, and one part of the frame is going to rub.
Kind of hard to see in the pic, but if you look at the top bar of the monitor frame, that is where it and the degaussing line are touching the cab frame. I guess I'm going to trim away a little bit of the cab frame for it to drop down in, though the need to mod the cab has me thinking about sizing it up in the GT one more time.
