Isolation for tube amps

Galen Carol Audio in San Antonio,TX sells inexpensive tube damping rings for small preamp tubes which I've found to be quite effective. I don't know of anything available for power tubes though.

"Herbie's Audio Lab" sells several models of very effective tube dampers for most sizes of tubes.

Don't underestimate the ability of a well designed isolation base - like the Silent Running Audio bases - to deal with airborne vibrations. The SRA isolation bases literally attenuate airborne vibration by converting the energy to heat. In my experience, there is no product that is as effective as an SRA iso base in dealing with the vibration problems inherent in an amplifier sitting on the floor - especially a tube amp, which tends to be more sensitive to vibration than a solid state amp.

Thank you all for your responses. Airborne vibration just does not seem to be discussed much and I would think this type of energy would be the largest contributor to vibration in all components. I suppose it is not addressed because one can not do much about it. I am going to continue to research this. Thanks again for your input

I use Herbies Halo rings and isocups and acrylic balls on my tube integrated. The Isocups are cheap and made a real difference. I am sure as Cincy bob says, a dedicated platform would be better, but costly. The other problem, not oftened mentioned, is clearance above the amp. If you put the amp on a rack, you need significant clearance above for isolation. A high amp stand may reduce that clearance, unacceptably. I use 845 tubes and need 10" above for ventilation. I know many do'nt put tube amps on a rack with other equipment.
