In my experience, very little help using damper rings with metal cased tubes. Noisy tubes just need to be replaced. Luckily, there seems to be a lot still available.

Not being able to see IS a problem. If a metal envelope tube is slightly microphonic, a silicone rubber "O" ring, where the envelope meets the wafer base, and a blob of high temperature RTV on top can be tried. For some added mass damping, embed a piece of lead, like fishing split shot, in the top RTV blob.

Pardon my ignorance-What is RTV?
Which one is the glass tube version?
what role does it play in the amp?
Thanks in advance for a reply.
RTV = room temperature vulcanizing. A link to a suitable Permatex product is provided below.
If you want a 12SJ7, with a glass envelope, look for 12SJ7GT.
