Tube amplifier is an excellent choice of high-end audio
equipment for its smooth, detailed and realistic sound.
However depending on it's type vacuum tube generates
"micro-phonic noise" resulted from its vibrations
and resonance's. The micro-phonic noise is prodded and
escalated by surroundings such as amplifier chassis,
tube socket and loudspeakers.
micro-phonic noise is depending on vacuum tube type
and brands. Basically weak construction and higher mutual
conductance generates higher noise.
have been varies efforts to reduce micro-phonic noise
of vacuum tubes, such as rubber rings and metal caps,
although its result was not outstanding.
Vacuum Tube Damper is an innovative solution resulted
from several years of intensive research and experiments
by the Allnic Audio Lab., significantly reducing vacuum
tube micro-phonic noise. All the components and materials
of Absorb-GEL™ Vacuum Tube Damper were carefully
selected and customized through repeated experiments.
Absorb-GEL™ Vacuum Tube Damper isolated and floats
tubes from primary vibration transmission media, such
as amplifier chassis or tube sockets. And Absorb-GEL™
Vacuum Tube Damper also absorbs direct airwaves from
noise reduction of Absorb-GEL™ Vacuum Tube Damper
was proven in our laboratory test and various field
tests by high-end audio listeners. Fig. 1 is a snap-shot
of oscilloscope showing dirty noise when tube amplifier
chassis was impacted. Fig. 2 shows very clear output
when Absorb-GEL™ Vacuum Tube Damper was used under
the same impact on tube amplifier chassis. Laboratory
measurement easily shows noise reduction rate up to
