Do they still make CRT tubes in China ?

Yes, I believe they still do.
There are so many tubes already in TVs out there in great shape just waiting to get swapped into a arcade chassis.
There is someone selling them. The prices do not seem to bad.

I wish converging a bare tube wasn't such a nightmare. I've tried two brand-new tubes so far and couldn't get close enough on them. Need a convergence bot.Or need to find someone that did this back in the day to teach me.

I thought that site comes up everytime someone talks about this, but that there were serious issues with their monitors or something?
Were they converged by hand in the old days or did they have some kind of machines?
If they were in fact done by hand once that means they can be done again, it's just a matter of finding out how.
Does this help at all with your convergence question?

Even then, if you try to do a full yoke swap, it still doesn't always work. I've tried 2 tube swaps, including swapping the yoke, and still couldn't get them to work. There are many members around here that have done multiple tube swaps and sell 19" monitors with rebuilt chassis all the time. If you really are in need of one, local413 always seems to have ones for sale with no burn and rebuilt chassis.

Don't you just display a convergence image on the screen and tune it in? I had to do a VGA monitor once that someone had wildly moved the rings on and that is what I did.
