These tube dampers are used for reducing the microphonics in your tube gear.

What is microphonics? The tube is constructed with many metal parts which are put together by welding them or by way of support with the mica wafers. The metal parts can vibrate when subjected to shock. When the metal parts move, their capacitance change which results in the variation of voltage they produce. As a result microphonics is induced. Microphonics is an inherent property of vacuum tubes, and all tubes produce microphonics to some extend. Some equipments are more prone to microphonics than the others, e.g. guitar amps.

How do these dampers improve the sound? These tube dampers reduce the vibration within the metal structure, thus minimize the microphonics the tube produces. As a result, music appear to be tighter in bass and having a higher level of transparency.

These damper rings are made of Aerospace High Temperature Silicone, rated to withstand up to 450 F. They are made to absolutely high precision and quality. The manufacturer of these tube dampers is also a major supply to NASA, 3M and DuPont, just to name a few. These High Density dampers will fit snugly on 9-pin tubes such as  10GV8, 12AT7 /ECC81, 12AU7 /ECC82, 12AX7 /ECC83, 12AY7, 12AZ7, 12B4, 12BH7, 12BY7, 12BZ7, 12FQ7, 2C51/396, 417, 5670, 5687, 5751, 5814, 5842, 5963, 6189, 6201, 6267, 6350, 6414, 6688, 6829,6840, 6900, 6922 , 6955, 6973, 6AN8, 6BL8, 6BM8/ECL82, 6BQ5/EL84 , 6BQ7, 6BW4, 6CA4, 6C45, 6CG7, 6DJ8 /ECC88, 6FQ7, 6GC7, 6GH8(A), 6H30 , 6GU7, 6N1P, 6N3P, 6N6(P), 6P1T, 6U8(A), 6V4, 7025, 7044, 7119/E182CC, 7189, 7199, 7308, 8416, EC86, ECC85, ECC86, ECC99, EF86, EL86, EZ80, EZ81, PCL82, SV83 and similar size tubes.

There are three sizes ranging from light weight to heavy weight. The light weights are for the slightly microphonic tubes and the heavy weights are for the severe ones. Use both by hobbyists and professionals. Most people use 2 dampers per tube, but you can also use one, or more to get the best result. The best place to position the dampers is near the mica supports.

When installing the tube dampers, make sure you don't cover more than one third of the tube surface (e.g. no more than 2 SUMOs) to prevent overheating. Why? Since the tube dampers are made of silicone rubber which is a poor heat conductor, with too much tube surface being covered, it will reduce the tube's ability to dissipate heat which would cause the tube to overheat and could result in shortening the tube's life. There are tube dampers in the market that cover a large part of the tube. Those are the dampers you should avoid. Not only they are more expensive, they are harmful to your vacuum tubes.  

Using these tube dampers is the most cost-effective way to improve the sonic quality on your tube gears. Whether you are an on-the-road musician or stay-at-home music listener, you will appreciate this tweak.
