Cory - good suggestion about the double sided tape.
what was the orig. bonding material between face glass and tube? just
curious....

On my 9835A it was Canadian Balsam a common optical bonding material.
I bonded the shield on my to the front of the case using epoxy. I had
tried tape but it slowly settled to the bottom of the case, I guess my
tape was not thick enough. In a very old TV I once had there was just a
sheet of plate glass set into the front of the cabinet in front of a
tube that did not have any implosion protection.

It's the understood chemical decomposition of the adhesive that holds the
screen shield to the CRT. It's pretty much inevitable, from what I
understand. The solution is to separate the shield from the CRT, clean the
face
of the CRT and reattach the shield. Some people don't reattach it, and some
people think they are risking serious injury - no opinion. Will the newer
adhesives hold up better? We hope so. -- Ian

A common trick amongst TV collectors with the large 23" round CRTs is to
carefully remove the tube and place it face down in a kiddy pool of lukewarm
water. Let it sit an hour or two in the sun and the faceplate will slide
right off.
To re-adhere the glass after cleaning, one technique is to use double
sided foam tape on the face around the perimeter; similar thickness to the
original PVA and holds well, especially if under slight compression once the
tube is reinstalled. -C
