Best tube dampers that you have used


I currently have a Thor Audio monoblocks TP-150, 8  EL-34's Sovtek tubes for each amp.
Was wondering in anyone's experience will tube dampers improve the sound quality.
Am hesitant to proceed as I have read that  tube dampers can melt from the heat of the tubes and sometimes
cause smoke. Any thoughts would be appreciated.

Uh, Kaitty, you can't "overdamp" the glass of a tube...Capish? I guess you're not much of a reality or comprehension guy.
Wolfie, I know you aren’t but what am I? One assumes whatever school you went to, if you did go to one, was some sort of fluffy two year trade school.

"One assumes whatever school you sent to if you did go to one was some sort of fluffy two year trade school."

Pop Quiz:  Is the above even a sentence, if so, in what language?

Mood rings make great tube dampers. You can tell if the tube is happy or not. A happy tube makes for a happy amplifier.
Forget expensive audiophile tube dampers, use red silicon "O" Rings are the best bang for buck to quieten tube microphonics used two spaced per tube.

Choose your size, don’t make them too tight, they "can" dent the glass over time.
