On my equipment, tube dampers helped on one preamp but not another. Ken Stevens, CAT manufacturer, suggested which tubes in his preamp to put them on in his preamp, and I got a nice increase in clarity and grit reduction. I used the pricey Tubesox.

Dampers didn't do much on my Joule Electra preamp, as Jud Barber predicted. Steve Herbelin was extremely good about taking them back.

I use regular teflon "O" rings at $1.50 each from a local auto parts store. They're for high performance applications and disperse the heat very well. They're recommended to be put around the getters only.

I use them on the amp and preamp both on SOME tubes but not all.

What tube dampers do you recommend?


No, just a waste of $, that's only ***. ..... yes, I've tried them. Rank'em right up there with snake oil and chicken lips.


Chicken lips fry up so good though : )  I have never tried tube dampeners because I like them naked.
