hmmm, the anode is REAL close to support ring. No way I could use the orig anode plug (no cup) that was on the 21CYP22. I ended up using a modern anode lead with a nice soft silicone cover, but even then it popped a few times until I really cleaned it and got a good suction fit. If that eases up at all in will arc. I guess I could try some kind of goo to keep it stuck. Has anyone else had this problem with a CTC-7 style mount ring on a later CRT (than a CYP that is).

the anode is only about 1" away from that ring...
