Silicon tube damper rings – 19-22mm to fit 12AX7/12AT7/12AU7/12AY7/5751/6922 preamp tubes and EL84 power tubes – resistance to high temperature to 240 degrees Celsius.
Combo amps are convenient packages, but can cause havoc on tubes. All of that awesome tone and volume from the speaker vibrates through the cabinet and can create tube rattle at specific frequencies, which can create anywhere between mild annoyance to full blown havoc!
What’s the solution?
Tube damper rings fit around your tubes to absorb the vibrations that surge through your combo. These tube rings take the brunt of the vibrations surging throug the cabinet, which allows the tubes to then operate as they were designed and only pass on sweet musical tones and no nasty rattling noises.
