### ⭐⭐⭐⭐⭐ Fits TAD 6L6GC- STR redbase
*by M***I on October 8, 2024*

These are great for dampening tube rattle. They fit my new combo amp perfect as they came w the larger tubes

### ⭐ Not for class A amps tubes get to hot.
*by R***N on May 14, 2022*

Had them for only a couple days they smelled very first time Then I heard one snap I realized that the tubes got too hot made them brittle I would not use them for a class a amp.

### ⭐⭐⭐⭐⭐ It depends on teh individual applicatiopn.
*by R***. on July 26, 2019*

I had difficulty with Arcturus 127 vacuum tubes in my preamplifier picking up transformer humthrough microphonic action. I switched the cathode heaters to filtered DC and I have aggressively filtered B+. When I put my hand on the tubes the hum goes away. These collars improved it but I can still hears some hum if I put my ear close to a speaker, but hot from a normal seated listening distance. They help.
