EL34 / 6CA7 / KT77

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. 32 mm
• Use tt-da15 for EH EL34
• 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.
