Silicon Tube Damper for 12AX7, EL84
Silicon Tube Damper for 12AX7, EL84
Vacuum Tube Damper made of silicon, helps to reduce noise and rattle of vacuum tubes. But it will not turn a bad tube into a good tube.
If a higher level of damping is needed, than use more than one damper per tube.
  • Inner diameter ca. 22 mm
  • Can not be used with JJ 12AX7 and other JJ preamp tubes with similar diameter and JJ EL84 and JJ EL844
  • Price per damper
BEFORE ordering check the exact outer diameter of the vacuum tubes and compare it with the diameter of the damper to make sure that the damper fits.

TT 12AX7 / ECC83 Classic
TT 12AX7 / ECC83 Classic
Tube-Town 12AX7 / ECC83 Preamp-Tube

The TT12AX7 impresses with its fine and detailed reproduction of the highs, which is maintained even at high amplification levels. Due to a higher H3 part, the TT12AX7 sounds significantly cleaner than many other 12AX7/ECC83 tubes, which makes the bass range appear much tighter. We therefore especially recommend this tube for styles such as clean, crunch, and metal, where high amplification and clear transparency are required.
