| GOLDEN DRAGON Tube Rings by Duende
Criatura considerably reduce distortion and
self-oscillation from audio tubes. |
| They
have to be slid around the top part of the tube and where they reduce
mechanical vibrations in the tube. |
| The
listener will notice improvement of three dimensional picture, a more
controlled bass and cleaner soundstage. |
|
| The
before mentioned effects are at their best when the tube ring is sitting
around the top part of the tube. |
| The tube’s
ability to radiate heat will be unaffected. |
|
| The
base ring has been manufactured of pure grade Teflon because Teflon has a
high specific weight and good |
| dampening
characteristics. Teflon can handle temperatures up to 260 degrees C.,
considerably above the typical |
| tube
working temperature of 160 to 220 degrees C. The titanium clamp insures an
intense contact between Teflon |
| ring
and glass tube. Titanium has been used because tube circuitry are normally
high-impedance designs and |
| therefore
sensitive to eddy-currents. Titanium, unlike other kinds of metal, does not
carry eddy-currents. |
|
| Duende Criatura tube rings are the result of years of design and
experimentation and can be used in pre stages, |
| phase
splitters and output stages. Improvement is recognizable in non-amplifying
and high feedback stages, but |
| sound
improvement is at its optimum in amplifying and low feedback stages. The
Duende Criatura tube rings are |
| available
in different sizes for most tube types. Non standard ring sizes can be
manufactured on request. |
| Tube rings can be
easily cleaned in either a dishwasher or with degreasing soap and hot water. |
