Can the glass on a tube be repaired???


I dropped a rare NOS tube and the top of the glass broke off. Everything else seems fine. Can the tube be repaired and if so, who does the repair work?

Thank you.

There are some glass audio tube repair services, you can try contacting them. Here's the website:

I watched the video. It was fascinating it. How did he evacuate the tube to create a vacuum? If it was there, I missed it?

This is pretty simple, if the glass is broken and you can put your finger inside the that 6SN7 tube. The tube is a goner
