New monitor or no?

[TurboC--]

I have a Wells Gardner 19K4616 19" with burn-in I would call "significant".

[Nipedley]

Hmm well I've seen monitors with "significant" screen-burn and it definately showed up when the monitor was on - less noticeable, but you could see it.
I'd recommend you hook it up and try it out yourself before you trash it - it's going to be in your machine, you should make sure you're comfortable with it.

Cant help ya with a new monitor I have had enough trouble myself even trying to find replacement chassis o.o

Where do you live?  I like K4600s.  I'd take it off your hands if you want to toss it.

You could also try swapping out the tube if the burn is that bad.

Swapping out the tube probably wouldn't be significantly cheaper than a new monitor, and then I still have to deal with 25 year old components?

Free isn't cheaper?  Well, except for the time involved.  Pull it from an old TV.  You'll have to find one that's pin compatible, of course, but that's not terribly bad.  Go to the dump, they may have a bunch there.  Or a TV repair shop might have one they're going to toss.

As for the 25 year old components, with the exception of the caps likely they're fine.  Of course, the only way to find that out would be to acutally *test* the monitor.  Do you have a way to do that?

TV tubes are the same as the ones in arcade monitors?  (boggle)

I'll test the monitor tomorrow if possible.  Going to try to setup AdvanceMAME on my (non-AGP) emu machine, see if I can get the vid card to 15 kHz, then if so, see if I can get a picture on the monitor.  Is it ok to use it on a bench rather than in the cab?  I guess as long as all the wires are hooked up and I don't touch anything while it's on.

I just did a 25" tube swap for my buddy Steve Mildenberger. The renters in the other half of his duplex house just had a garage sale. In the sale was a 25" non-working Magnavox tv set from around 1989. Anyway, nobody would buy it so they set it on the lawn with a "FREE" sign on it. I saw it, opened it up and looked at the tube. It was a perfect match. So we got the whole tv set for free. I carefully took out the tube, swapped everything over, fired it up and this monitor looks perfect! It's like brand new. The old tv set cabinet goes to the dump next week.

The monitor I put this tube into is a Wells-Gardner 25K7191.

As long as you use an isolation transformer, yes.

Well that's interesting.

It sounds like you may be getting in over your head on this one. I think you should give away or sell the complete monitor to fellow forum members (or ebay it) and buy a new monitor instead.

Well I have a bachelors in EE.  That doesn't mean I know the specifics of every real-world application.  That's why I ask, cause I want to be sure before I do something.  If I have access to lots of tubes, then seems like I should take advantage of it.  My friend also worked on TVs for years.  Just a question of not screwing up the soldering.

This link will give you the info you need re: matching up a tube to your chassis.  http://www.8liners.com/datatech/monitor.html .  If you find it hard to source a perfect match you can always swap the yoke from your monitor onto the new tube (your t.v. repair friend might need to help you with this) then it will be a perfect match.  All low resolution tubes are the same (except for Sony Trinitrons) whether they're used in a t.v. or arcade monitor.

Thanks a lot for the info.
