I bet Mrs. Drysdale and her drinking buddy, Mrs. Thurston Howell III are quite pleased to be able to watch the Larry Welk show in such style again. LOL!

Even when you put the safety glass back on I'm thinking it does not offer the same protection as it did when it was bonded to the tube.

True it does provide some impact resistance but overall if the tube breaks it's still going to scatter glass all over because the plastic lamination that's supposed to hold it together is gone, possibly even worse because now you have two layers of loose glass.


Anyone else have any thoughts on this?

Eric

All of this is true, it is not as save as it was originally. I just think of probability of a disaster in this case. It most likely only implode if I really slam something into the crt

I was just speculating Doug, we have to do what we have to do to fix these things sometimes

I have to remove the safety glass from a NOS rebuilt roundie sometime and I'm not looking forward to it.

the tube is relatively fresh being built in 1980. No cataracts and the bond is probably still pretty tight.

I have an otherwise excellent 10BP4 that has a badly scratched up face. I was wondering if the face would stand up to a little wet sanding without imploding

It seems as though the 21FBP22 uses the same implosion protection as a PVA-type tube w/the PVA removed, that is, a form fitting safety glass that is taped around the rim, but not bonded to the CRT.

I have heard that the 21FPB22 has no implosion protection, but this can't be true as I have 2 sets that use it and none has a seperate flat safety glass that remains in the set.
