Looking for CRT 21FJP22 or 21FBP22.

Tom, agree and can second all you said. I too have had to attach leads broken flush with the glass. Careful picking at it gave me the opportunity to attach wires.

To thread the base I used thin gauge wire wrap wire. I tack solder to the ends of the wires from the CRT and thread them through. I use fast setting epoxy to attach the base to the tube. Never been unsuccessful doing this.
