I own Herbie's tube dampers and had them installed on both my microphonic CCa and Amperex Pinch Waist tubes. The tube dampers didn't solve the microphonics.
Follow Ups:
Try some vibropods under the unit. Anything to isolate the unit from the environment will help.
Thanks. I use Symposium Rollerblocks Series 2+.
Hi!Amazing...3 years ago since I changed the Chinese provide 6DJ8 tubes on my ARC-SP-9 Mk/2 hybrid preamp by Amperex Jan USN white label & gold coated pins 6922, & till today NO microphonics at all...my ARC is stacked on my McIntosh MR-78 cabinet fitted tuner on top of 3 Vibrapods Cones...NO minor problem since i changed the supplied Chinese tubes and I listen 12 hours EACH day...7 days each week. BTW...I'm a pensioner 63 years old...all the time at home...so I can enjoy turntable & radio or Cd player a lot!.
Could be that ARC is better designed & or built that your tube preamp???
