It looks like a DIY. I wonder if it's worth buying.

Thanks again Chris. I wonder if you can hear the difference in sound.

Try them out and see if you hear a difference...or...maybe a little ring toss to pass the time....

The Herbie's have soft contact footers to do the dampening, he uses the Teflon for clamping strength only, where the Duende's are all Teflon and look as if they would be too hard to make a good contact??? Dunno, but you can pick up Viton O rings, which are high temp and soft as well, for about 10 cents each by the bag...

Or you can replicate the Herbie's with Teflon o-rings from McMaster Carr. Dirt cheap.

Enjoy,
Bob

Levi,

The Herbie's work well (I own them). But, before you go and spend $7.95 a pop on Herbie's...try a mortite 'hat' on your tubes.

Flatten a dime sized piece of Mortite Rope Caulk (or Dennis Rope Caulk...available thru Ace Hardware dealers) and place on top of tube, flatten it gently to tube....and allow the tip to poke thru.

It works great on the small 12ax7's and 6922's I have...dampens microphonis to a point of non-concern. And, it's cheap - maybe $8.00 a package (that'll do probably 10,000 tubes

). I haven't used them on larger (and hotter) amp tubes...but they are great on the smaller ones.

I use the Herbies WITH the mortite 'hats' (yarmulke, if you like

)

Do not use Plast-i-Clay on them - it will melt. But, rope caulk will not and hasn't in over 3 years using it.

Enjoy.

In my Modwright CDP and pre, I find that tube rings deaden the sound too much for my taste. Instead, I damp the chassis using Dynamat and plasti-clay (thanks, ChairDude), leaving the tubes to breathe.

Microphonics, especially prevalent in the pre before, are killed while allowing the breath of tubeliciousness to come through.
