EAT Cool Damper
Cool Damper is a radical new device. It
brings exceptional acoustic performance and function to your system by
delivering sound that redefines the tube dampening category.
MULTIFUNCTIONAL VALVE RING
The Cool Damper is
a radical new device for the tube accessory industry from
EAT – EuroAudioTeam.
This beautifully crafted audio product offers much more than simply adding a
new styling twist to your valves by surrounding them in new, fashionable
colors. It brings exceptional acoustic performance and function to
your system by delivering sound that redefines the tube dampening category.
Carefully chosen materials for our Cool
Damper device allows using it as a truly effective
vibration-consuming damper. This results in reduced distortion from
the tube circuit, as well as vastly reducing the tendency of most vacuum
tubes to act in a microphonic manner. In addition, the sound from a
component utilizing Cool Dampers
can be heard to have more controlled and deeper bass, a cleaner sound stage,
crisper and greater dynamic range, and better focus of the entire sound
The Cool Damper
also reduces the operating temperature of the glass envelope of an electron
tube by about 10%, which of course acts to appreciably extend the lifetime
of the tubes.
The Cool Damper is
a result of many years of rigorous research and development. This
high-fidelity, consumer friendly product is easy to install, and fabulously
simple in design. We found, from all tested materials, that the most
suitable is a relatively soft aluminum extrusion coated with a special
blended mix of Teflon and Carbon composite PTFE. The precise shapes of
the EAT Cool Dampers
are finished with long-lasting anodic oxidation colors. This makes
these cooling rings an aesthetically attractive, as well as functional,
accessory for your valued vacuum tube equipment.
For flexible and easily detachable contact of the aluminium body to the
sometimes erratic cylindrical surfaces of various tubes, we use six special
carbon-teflon composite stripes (V profile). Appropriate design and
materials of the Cool Dampers
compensate for the naturally resonant tendencies of both glass and aluminum,
and work to transform active vibrational energy into thermal energy, which
is then dissipated as heat radiation.
Tube dampers in one form or another have been around for many years, but
these from EAT are
so much more effective than any previous efforts that they deserve to be
auditioned on their own merit.
How it works?
1. Dampers are from the factory preinstalled. This means 6 pieces of the V
profiles are positioned in the middle of the hexagon.
2. By moving the V profiles along the face away from the corner it is
possible to move it closer to the center of the hexagon and thus the valve
wall. By this simple expedient, tubes from 19 mm to 22 mm in diameter
can be accommodated, which covers most eventualities.
3. Diameters of the most valves are usually smaller on the top of the
erratic glass envelope than on the bottom. By sliding the valve over
damper in an up side down position you can easily install it. In a
case, damper slides down the glass or is to narrow just change position of
the V profiles.
Where do you use
EAT Cool Dampers?
Inner side of the damper has 3 × 6 channels for a wide range of diameters
from 19.5 to 22 mm. This means it fits to the following valves:
