Ayep! Yes indeed!

But you have to get it before the pieces are entirely lost. AMHIK.

But if you are going to be a scrub nurse for a kinescope you'd best have a jumper between the anode connection and what is left of the outer coating.

Otherwise at least post vids of your activities, discoveries and resultant observations.

Edit; Soapbox time here: There is never any such thing as a fully-discharged kine!!!! Read this and heed it if you will. Glass can retain residual charges through a process of adsorption. Thus a successfully-discharged CRT can sometimes self-recharge to bite you when you thought it was finally laid to peace in the emf department.

I used to blame this phenomenom on my own forgetfulness.

The latest that shares this info I have is http://www.repairfaq.org/sam/crtfaq.htm

Read it as you may FYI--be such as it is. It at least tells me that God or Fate is not out to kill me whenever I handle an old kine.

Like firearms the CRT should never be assumed--or even mildly considered--an "unloaded" device.
