Looking for a new Amp or Preamp? If you're after tubes, post over here.

RE: Tube Preamp Vibration Control Suggestions?

They are called Vacuum Tubes for a reason.
A vibrating filiment doesn't transmit any vibration 'thru the air' since there isn't any.
All coupling is thru the mechanical connection of the tube thru its supports and than to the base of the tube, firmly socketed. Mechanical properties of the 'wire' in question is what provides damping initially.

Some kind of hi-temp O-Ring around the envelope? (Viton? Silicon? Nitrile? EP?)
How hot does a power tube get on the outside?

But I would also suggest that somehow the tube socket gets isolated from the chassis to prevent coupling in EITHER direction.

Any traction with such an idea? new Product?
