What are these? tube guards?

Pardon my ignorance, but in the image above, what is the ring around the tube? What are they used for? I've seen a few WA6SE photos with this, and many without. Do these ship with all tube amps? If not, where can one buy them?

I'm pretty sure it's a tube damper, designed to reduce the microphonics due to vibrations that are present on many vacuum tubes.

 

Some pretty similar looking ones here:
