Tube dampeners on ARC gear ... FREE TWEAK


Here's a cheap (free) tweak for owners of ARC gear using the black tube dampeners. If you move both dampeners as far up toward the top of the tube as possible without having the top one fall off, taking care that both dampeners are solidly touching each other, you will get better dynamics, bass, mids, highs and a lower noise floor. Try it ... you'll like it.

I have a friend that uses ARC tube dampeners on his "other than" ARC amp.

What kind of measurements have you don't to assess the "thermal flow?"  Can you supply a study or a link?  Thanks ...

Sure, you can use the inexpensive ones, that is if you're enamored of that rolled off closed in sound. Like everything else in audio and life sometimes you get what you pay for.

Hey it's not voodoo, all they do is to damp the cheap thin glass of todays new tubes from ringing, nothing else. Nothing inside of the metal tube structure itself anodes, cathodes, grids, getters, heaters ect, as that stuff is all bonded to the base material. If you want dead thick glass you have to look at NOS tubes. 

And no, any type of tube damper will not stop a tube from being microphonic.
