What kind of tape on yoke wedges, etc.?

[KPW66]

I'm doing a tube swap on a K4600 and I have two questions:

1) how should I secure the rubber wedges to the tube? Tape? What kind? The current tape almost looks like medical tape but it's getting loose. I understand I may have to adjust them but ultimately how should they be secured?

2) same question for the inside of the yoke where the little metal strips (magnet?) are placed. One of them came loose due to old tape and I'd like to put it back exactly where it was before installing the yoke.

Thanks

I think the original tape is a double sided heat resistant tape called..

"Kapton Double-Sided Thin Polyimide"

Applied to the wedges like in this pic

I've used "Sellotape Permanent Double Sided Sticky Fixer Pads" for the wedges before and they worked pretty good.

I use Gaffers Tape to hold down convergence strips.

Seems to be the closest thing to the original tape used and holds well.

Also has a service temperature: 50F to 200F

I vote for the Kapton/plolymide tape. Used widely in electronics manufacturing. Stable at a high range of temperatures and it's an electrical insulator. It's not that expensive and a roll will probably last most people a lifetime. And as Elektronix said, it was likely used originally on those wedges.
