Herbies tube dampers

Interesting, I have had Herbies tube dampers on my input tubes for years. But based on this thread, I just removed them, and I think, there is a little more sonic life in the music without them.

@ozzy,

agreed. In my experience (I tried Duende Criatura, EAT and several others whose names I forgot) anything that touches the tube around its glass bottle ultimately dulls the sound. Two tweaks that seem to work: Mad Scientist Audio Tube Toppers and putting a 1/4in ball of Bluetack on the top of the tube. YMMV

antigrunge2,

Are you using both of those items at the same time?

antigrung2,

Looks like the Mad Scientist no longer provides that product.

So, are you saying that a ball of blue tack on the end of the input tube helps? Hard to believe...

I use the Mad Scientist toppers on my WE 435 and the blue tack on 6l6GC and 300b tubes. Bluetack has excellent damping characteristics.
