I have a really nice Space Wars machine. When I got it, the monitor fired up right away no problem. After a few months of owning it, it would take 4-5 minutes for the picture to come up. I then had the tube rejuved, and ever since it went from 20 minutes to now taking a minimum of 30 minutes for the image to come on the screen, though the game will play blind the minute it is turned on. When the picture does come up, it starts with the images being very large, then they shrink to their normal sizes over a few minutes until the pic looks perfect and stays that way for hours if I leave the machine on. Is the heater going bad? Did the rejuv wreck something? Will a second rejuv help? or make it worse? Anyone got a nice B&W tube for sale?
 
I've been troubleshooting my Space Wars machine trying to get working along with a lot of research. This sounds more like the video board needs some repairs, probably on the high voltage side. If it is the tube, take heart, as I'm told a new one can be purchased for around $150.
 
I hate to say this cause every time someone says this to me it is not it. But do those old B&W tubes ever need cap kits?
 
Tube......................

I may have one, but I'm sure it's loaded with burn.

I figured it was the tube. This one is burn free. Should I try another rejuv? Couldn't hurt? This is the same tube that the Motorola 1001 B&Ws from SI and SID use, correct?

From what I understand is that the monitor is a 19VARP4 in B/W Cin/Vectrobeams and bare CRT replacements are available.

Here is some great detailed info here:

Yes, those can be used, usually they have a ton of burn... I dug out a 19" battlezone monitor with a decent tube. ther is burn but it has a nice bright tube.
