While I wouldn't normally post an eBay listing on here, the situation of finding NOS CRT's may excuse me. Saw this on eBay, they look like all later model CRT's, but some forum members might be interested and it would keep these from winding up at the dump. Not my listing and I have no interests involved:

I didn't see this in another thread, if it is, moderators can set the dogs on me...

While I don't see a lot exciting there are some folks looking for some of those tubes. I suspect most of those 19v/25v types are for 70s sets? There is some interest there. This company has been sitting on a very nice inventory.

I beat there are some CRTs in there that will fit wells gardner crts that are in arcade games. I can tell you those are hard to find and wanted to a lot of people restoring arcade games from the 80's. I know I paid a pretty penny for a used one with no burn in for my ms pacman.
