I have used many forms of vibration dampers for tubes in the past with varying results.
Pearl coolers,EAT dampers,Duende Creatura rings etc etc.
I have come out with an idea after making a simple experiment with a piece of soft rubber
cut with a scissors.My tubes run down the depth of the amps in pairs (five of them),
plus one 6SNGT far at the back.
When i inserted the pieces of rubber between the tubes so that every pair becomes a unit,
i noticed much less vibration than any other dampening device!
Standard tests like knocking on the amp's chassis or tapping on the tubes showed significant
reduce in tube "ringing".
It looks like when two tubes are "tied" together they tend to resonate much less ...
So i am thinking of fabricating something like a double C construction (two c's ,one facing opposite
to the other) with silicone inserts (O-rings) cut into each C.Then each tube will be half-embraced
by each C section and both will be pressed into the C's with a larger O-ring that will push each one towards the other.The material will be cut out of 1cm Teflon sheet making it immune to heat.
I will have to make some tests as to which is the best place along the tubes to place the damping
and i will report back.
Anyone has tried something like this or has something similar to propose?
