Bob G shot me an email, 30 minutes later it was mine. 12UP4 is kind of weak, but should make a picture. It survived a hurricane unscathed....
It has all the knobs an stuff, I took them off for transport.

Nice score!
I thought you only cared about early color RCAs...

Meh, the random porthole deserves to be saved too.
Update: After trying to revive the CRT (didn't work), I let it be on the floor. Today I went upstairs to move it, and I noticed the getter is all white! WTF? Yup, a crack all the way around the neck just like what happened to the prototype CRT. So now I'm wondering: is running a tube for only a short time creating enough of a temperature gradient across the glass to cause it to crack? Is that even possible?
Meantime, I put the gun in a bag and taped up the neck of the tube. Maybe one day I'll have a chance to put a new gun in it...

would a 12LP4 sub ? look at the bright side the crt wasn't that good so the fact that it is not useable now would be worse if it was good , the protype set went to air ?
i haven't had any bad luck yet of a metal/glass crt going to air for no reason but i'm sure it will happen one day , perhaps it had a small crack from the quake or transporting and you didn't see it and it decided to expand , this is why i was afraid to remove a 19ap4 from a dumont to clean the screen and the face of the tube , i did have a 19ap4 shipped to me and it arrived ok and was put into another dumont set and it is ok but like i said the risk is just too high.
