WOW! That is VERY usefull! I have a k4600 to put in this, So I guess I will look at my Galaga for how I should mount it.
Anyone have a 25" Galaxian? Need information

Yeah- I've still got one.
The monitor pooped a couple of summers ago and I haven't messed with it.
Electrohome G02. That's the one. Same monitor that came in some Sea Wolfs and cockpit Missile Commands. It has about 15 user-adjustable coils on the neckboard to electronically set the convergence. Good luck with that.
Go ahead and naysay all you want- 25" worth of scanlines and 8-bit pixelated 16-color glory is what you want in your face when your Galixip is busting convoy after convoy of galactic ass.
There.

That deep DOOoooo DOOooo DOOooo sound is as cool as the Space Invaders thump thump thump

Just curious have you ever put a 25" monitor in a galxian/Galaga cab for one there is no room for a plastic monitor bezel. You wouldnt even see it on the top and bottom and when the glass bezel is in place again you cant see any of the monitor frame.Just thought I would point that out.

Yes it is.
If you can get photos of the front and monitor area, that'd be awesome. I'd really love to see how the 25" monitor lines up with the bezel...
And, if someone has a working one to take pictures of...

If the 25" monitor was used because they ran out of 19" monitors I can see Midway just adjusting the height and width of the picture to fit the bezel area, and not take advantage of the whole usable screen area.
I wouldn't do this to mine, but it would look really cool if someone stuck a flat panel that would fill the entire bezel area like those PinMAME guys do.

That looks good for PinMAME. But flat screens in a classic arcade machine are like sticking an electric motor in a `57 Chevy.

Lol, I would never do it myself, most flat panels I have seen just replace the monitor and keep the bezel. What I am taking about is that the monitor would replace the bezel and what ever game you load up in mame it load up the matching bezel. And not in a real cabinet but a repoduction cabinet. The cool thing would be that you wouldn't need a vertical and horizontal mame cabinet. But this is getting off topic.
I bet the 25" looks great in galaxian!

Do think it would be bad if I installed a 4600 instead?

The early Galaxians shipped with one of two monitors, both of which are (to me) interesting beasts:
Electrohome G02 - 25"
Wells Gardner K4500 - 19"
Both of these monitors are, for the most part, modified television designs. Both of them use a delta gun CRT (hence the massive convergence and yoke assembly).
Both monitors have a somewhat different mounting arrangement than we're used to - the G02 has such a huge chassis that it's mounted to the inside of the cabinet wall. If your Galaxian ever had one of those, you'd be able to tell from the bolt holes in the cabinet. Furthermore, the tube in the G02 is extra deep - it's a 90 degree tube, not 100 degree like other 25" arcade monitors.

No not at all, I thought about doing it to mine, but my 4500 still has a good picture

Having the bezel reproduced on the screen would be kind of nifty.
But then you'd have to deal with playing a classic game on a flat-screen monitor. And that's awful.

Man Ian, your depth of knowledge is so so impressive! But aren't pretty much all TV's made after 1980 using red green and blue guns? I don't know much about this stuff...
Thanks
If you used a 3D lcd, you could simulate the curve effect of the tube too. It would be funny wearing glasses while playing.

Correct. All color TV's use red, green and blue guns. It's been that way since 1955. But the difference is the *arrangement* of the guns. Traditionally, there were delta gun CRT's - in this setup, the colored dots on the phosphor screen (and therefore the electron guns) are arranged in a little triangle. Look very closely at a 60's color TV tube, and you'll see rows and rows of these little clusters of little round dots.
Then along came Sony. They had a better way. They turned the little triangles of dots into little blocks of vertical lines. They arranged the electron gun assembly so that everything was in a horizontal line. They changed more than just that - changing the shadow mask into a mesh, cylindrical face CRT, etc - and called the finished product the Trinitron. The Trinitron had lots of advantages - not the least of which was the fact that all the guns were in a single line. This simplified the convergence greatly, and allowed the driving electronics to be simpler. By the end of the 70's, pretty much every manufacturer had their own version of an inline gun picture tube.
So, all the normal arcade monitors we know and love are in-line gun tubes. Converging one of these is a bit of a pain, but not that bad. All that's required are adjusting some little magnetic pieces on the neck of the tube. The old delta gun sets, on the other hand, require mechanical and electronic convergence. The convergence assembly contains both permanent magnets and magnetic coils. Converging one of these requires precise setup of the blue lateral magnet, the positioning of the coils, and the adjustment of nearly a dozen electronic controls. This is all necessary in order to get the guns aligned with each other, and lined up on the screen.
The electron gun assembly in an inline set is simpler, and I do believe it helped in allowing them to make 100 degree tubes in the first place. Early color tubes were actually 70 degree deflection. For the longest time, the largest color set (and pretty much the only size color set), was a 21" round tube in console cabinet. If they had made the face of the tube any bigger, the tube would have been too deep to fit through the door.
