I found this thread wherein the threats of X-ray radiation get called out. http://https://forums.arcade-museum.com/showthread.php?t=392981&highlight=Tube+swap+g07
A couple of thoughts: 1) I thought the crt radiation thing was a myth. 2) I have young children and am not an electrical engineer, should I be doing this?
you've asked about 60 questions in this thread already. they're the kind of questions where if you have to ask them, you probably shouldn't be doing it.
as for that thread, the core lesson is that you can't just simply use your multimeter and take an ohm measurement on the horizontal and vertical windings of the yoke and be like "ok, it's close enough" and operate your monitor like that.
and if X-rays were a myth, why do monitors have a high voltage shutdown?
once again, if you weren't culturally aware of this feature, you should probably spend your time just playing your games instead of engaging in the laborious task of tube swapping. people blow this screen burn thing so far out of proportion it's to a point where if someone posts an ad and mention "burn-free tube" it seriously pisses me off. especially when it's a game that by virtue of how it was programmed could ultimately burn the screen again anyway. you'd have to obviously have the game on for a very long time to accomplish this, and it almost never happens in household use, but I'm sure there's someone out there that's done it.
there's another lesson from that thread. it essentially means that if you run a TV yoke instead or a tube that isn't 100% compatible with the chassis you're running, a number of things on the the monitor can operate outside their tolerance. chief among them, X-rays. I don't care if a K7000 is "close enough" to most TV yokes, I'm swapping the yoke.
if you do enough research you can actually skirt around having to converge the monitor again. in all the tube swaps I've done, I've never had to do it. just something to consider.
the last item I'd like to point out is there's a massive influx of people getting into the hobby now that aren't taking the time to learn how the hardware works. 9 years ago I didn't know jack shit about video games, and I too thought the tube manufacturer was indicative of the "monitor chassis" (common mistake; people saying "I have an RCA monitor"). I do this professionally now, because I took a lot of my free time out to learn how these things work, and you get good at it when you actually know what you're doing first before you set out to work on things.
otherwise, sell your machines and go back to consoles. they were intended to be repaired and maintained by people like me. it's not easy enough that your grandma can do it, contrary to what people may believe. if you look in the repair section you'll actually see recurring users that seemingly have nothing but problems with their games. it's because they don't know how.
that's it, I'm done being a prick with a lengthy rant now.
