Tubes, to damp or not to damp?

I’ve used Herbies UltraSonic SS dampers without any over damping effects. They prevent acoustic vibration from speakers or resonance from audio racks, especially on components with exposed tubes. Also good for tightening up the bass on some tubes.
The ring type dampers can suppress overtones and harmonics.

I generally don’t use them on tubes enclosed in a component unless a tube has some microphonic issues.

OP, do you think your tubes need damping or are you experimenting?

I’ve used Herbies dampers in the past on various components but I don’t seem to need them in my latest system. Currently there isn’t any benefit to damping.

Whether you're a fan of tube damping or not, O-rings are too tight and apply pressure on the glass.

The stock dampers on ARC amps are probably ok since they selected them or they're proprietary.
