Its Gota Come OFF!. Chemical guys what would i Use?. BONDED YOKE!.

Electron gun assembly took a dump in a tube so I MUST salvage the yoke which is bonded.
The last Time I removed bonded yokes from a CRT the glass came right with it. It seemed impossible removing it without breaking the glass. If I can avoid breaking the glass great.
If it comes off breaking the glass what could I use to remove the bonded glass left on the yoke without ruining the yoke varnish. From what I understand there is a coating to insulate the yoke wires. I would imagine it would resist most chemicals just want to loosen the bond / glue that keeps it to the glass! Thanks.

The yoke is glued to the tube? Whats this on, never seen one like that.
The problem is your not going to find anything that will soften the resin without damaging your coating on the yoke windings.
I would try working a razor blade down between the glass and resin and see if you can get it to pop off without pulling the glass with it.
Post a picture and maybe I can suggest something better.
 
Job done, however what a bitch!
The glass came with it attached to the yoke bond...
Had to pry the glass away from the bond with a flat head.
It's a very tight fit on the replacement tube... There is no way to remove the bonding without tearing winding.

A lot of newer monitors have bonded yokes. D9200's, D9400's, D9800's and some Neo's and Kortek's. Really sucks when you need to do a tube swap. I think the Polo's had bonded yokes too.

Chad's right. Its a bitch to get those things off but they will come off if you try hard enough.

next time try a heat gun to soften the glue but not the varnish on the windings.

Its not glue, I think its either plastic epoxy or just plain and simple epoxy. Whatever it is its really hard and bonds really well.
