vacuum tube top question

Hi all,

I'm getting around to restoring my 38-7, and I've noticed a problem with a vacuum tube.

Coming out of the top of the tube is a very small wire. On top of that is a little metal cap, which is connected to wire that continues the circuit.

My problem is that this cap won't stay on the tube, and so the circuit becomes broken.

How can I keep that cap on top of the tube?

Im assuming the little wire coming from the vacuum tube has to touch the cap to keep the circuit connected.

If this doesn't make sense to you guys, I'll try to take some pics to explain better.
Thanks for your help.
