Do tube damping rings work?
We have found that damping tube sockets can sometimes be effective at reducing microphonics, but damping the bulb glass is much more effective and the results more consistent amongst various tubes and components. These dampers reduce tube microphonics, but the sonic result is poor.
What is tube damper?
ABOUT. These custom made high temperature silicone damper rings will prevent your tubes from dancing along with the music coming from your speaker. Commonly referred to as “tube rattle” this metallic ringing sound can occur in any tube amplifier – especially a high power combo amplifier in a small package.
What is a damper ring?
The damper ring has a cross-sectional shape perpendicular to the circumferential direction. The cross-sectional shape has a depth in the radial direction, and a neutral bending axis that is spaced from the engagement surface by more than half of the depth. 
What kind of ring does a tube damper use?
For years we have tried different tube dampers and that are available and standard silicone “O” Rings but the sizes available only gave a minor reduction in rattle. The harder durometer standard rings just didn’t have the density to absorb vibrations very well.
How does Herbie’s elastomer ring damper work?
Elastomer rings can fuse to power tubes or eventually crack and wear out. O-Rings placed around tubes have no place to disperse vibrations; by contrast, all Herbie’s dampers feature isolation pads to absorb and disperse vibrations into their surrounding “C” ring.
How big is an extra large eurodamper ring?
The only power tubes we do not recommend the large EuroDamper rings for are the sovtek and chinese 6V6’s, EL34’s and small bottle rectifier tubes where the tube itself is 1/8″ smaller than the octal tube base is. The Extra Large EuroDamper measures .375 tall with a 1.500 inside diameter and a 2
What kind of damper is used for extension sockets?
Absorb-Gel (Allnic): These are extension sockets with a gel material inside. We have found that damping tube sockets can sometimes be effective at reducing microphonics, but damping the bulb glass is much more effective and the results more consistent amongst various tubes and components.
