remember for any signal tube, what we are trying to do is to MANAGE microphony, not eliminate it
Anybody have ant thoughts re using 2 Herbie's tube dampers on 1 tube?
I'm already using Herbie's UltraSonic SS on the 6SN7s in my amp. I'm definitely happy and believe they make a positive difference. I've noticed that in some pictures of a number of tube amps that some folks are using more than one of the "rubber" style dampers on their tubes. Does anyone have any ideas?

Save your money and get these, not too tight just a snug fit, measure the diameter of your small and big tubes and reduce it by 2mm for the ID of the o-rings needed, for them They are high temp very high quality silicone o-rings, for industrial purposes. They stop the thin glass of todays cheaper Chinese/Russian tube from ringing, they WILL NOT! stop a faulty tube that has gone microphonic, neither will any other tube damper. BTW!!! There is no such thing as overdamping the glass envelope of a tube https://www.ebay.com/sch/i.html?_from=R40&_trksid=p2334524.m570.l1313&_nkw=red+silicone+o+ri... Cheers George |
Glad you said it, @georgehifi. An '"overdamped" tube glass envelope is the same as an overdamped loudspeaker enclosure: an oxymoron. Both should be as non-resonant as is reasonably possible to make them. The cases of electronics as well, for that matter. And turntables, tonearms, and phono cartridges, and the walls, floors, and ceilings of listening rooms. |
I’ve used the same silicone O-rings as George (but- from McMaster-Carr), for decades. Also agree (from my personal perspective); there’s no such thing as over-damping resonances. I consider anything that adds or subtracts anything, from an original signal, as distortion or coloration. Then again, when I had my shoppe; I catered to all tastes/preferences. This is definitely one of those try-it-and-see-for-yourself situations. iow: EXPERIMENT! https://www.mcmaster.com/silicone-o-rings/high-temperature-o-rings/ |
