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.

OP

I put mine on both close to the top but not touching.  I have heard microphonic effects in the sound from time to time in the past with no dampers on and this seems to solve the problem though I am sure there are other ways as well. 

I think GK mentioned liking the Herbies dampers if I recall correctly.   Don't recall why.

Lots of information out there from many credible sources about tube microphonics.

No voodoo there.

Which dampers work best when needed?   The standard ones that came on the tubes in my Arc pre-amp seem pretty simple and effective.   Others might be better or at least produce different results for sure.   YMMV most likely.

OP next time I open that sucker up I will check the dampers and try that.

I last dabbled with them quite a ways back. Its possible they are set up as you describe already but not sure. I know they are at the top not far apart but not sure if actually touching. Could be....
