Makes tubes less microphonic and lowers distortion
Duende Criatura tube rings or tube dampeners considerably reduce distortion and self-oscillation from audio tubes. They have to be slid around the top part of the tube where they reduce mechanical vibrations in the tube. You will notice improvement of three dimensional picture, a more controlled bass and cleaner sound stage.
Duende Criatura tube rings are made of pure teflon and titanium. Simply slide the ring over the top of a vacuum tube. They reduce mechanical vibrations and stabilize the operating temperature of the tube's filaments. This not only creates better conditions for the operation of vacuum tubes but also improves the tube's longevity.
The precision-machined teflon base ring is very dense which provides excellent damping properties. They can withstand temperatures of up to 260 degrees, which is much higher than the operating temperatures of vacuum tubes ranging from 160 to a maximum of 220 degrees. A pure titanium clamp is used to provide a strong and stable pressure over the teflon ring to increase the effect. Titanium has been used because tube circuits are sometimes sensitive to eddy currents. Titanium, unlike other metals do not carry induce eddy currents. Duende Criatura tube rings are very durable and last indefinitely.
All vacuum tube types and sizes in any part of a circuitry will benefit from Duende Criatura tube rings. For proper effect the rings should be placed around the top of the tube as shown in the photo. This will allow the tube to properly dissipate heat.
