John Yep…this really works. And you don’t have to spend $15/tube on those ridiculous retail dampeners!!!
 
Mike Fifteen rounds of plumber's teflon tape held by a narrow band of heatshrink tubing around the centre of the tape gives even better resonance damping. Loud passages much cleaner.
   
Michael S. Damping can be overdone. I overdamped the output tubes on my preamp and the sound became lifeless and dead. Damping can be very good though. Try to find the balance of reduced microphonics while retaining the zip and zing of tubes!
