I use damper rings on all the combo amps when I replace the tubes, I have yet to have a problem with micro phonics. extra protection never hurts to have

Apart from the slight odor of cooking silicone, these appear to work as advertised. If your amp has metal shields over the preamp tubes, don't bother, they will not fit. High freq ring I suspected as microphonics is no longer evident on my Fender Princeton Reverb
