Thanks @buellrider97, I've been thinking about tube dampers. I have read some good comments about them.
Microphonic from Vacuum Tubes?
HI, I have a question regarding microphonic from vacuum tube. I have a Cary SLP-05, and I've changed the output gain tubes to some NOS RCA, and also recently purchased a pair of Linlai for the balanced buffer stage.
I now occasionally hear a loud pop in the music. It doesn't happen very often, but when it does, it is quite loud. This happens when I am streaming digital music, so it can't be those occasional pops you hear from vinyl.
Can someone tell me if this loud pop possibly caused by microphonic in my tubes? if so, how do I track down which tubes? My guess there is no easy way but change one tube at a a time, which can be extremely time consuming. Also I don't own a tube tester. I wonder that would help tracking it down.
Also I read something about vacuum tube damper rings, would that help calming down possible microphonic?
I still consider myself a newbie in tubes, so any hep will be appreciated. Thanks very much.

+1 @wolf_garcia , Wolfie nailed it ! I appreciate your prospective . Personally I’ve run into brightness issues when doing any exorcisms as the silver adds too much brightness and causes the demon screams to hurt my ears. However Silver gel works great on mold and bacterial issues. Joking aside Ralph has more knowledge and experience than the rest of us put together, I’d advise following his direction. A logical SPOC like search working backwards from present will reveal the culprit. And always employ “ Rule 62 “ on Agon, “ I can’t take myself so damn seriously “. 😆 |
When you make a change and things go south its a good bet that the problem is associated with something you did. However, that bet can also blind you to what is really going on; pursuit of the problem in that manner can yield no results if its not really the issue. Equipment turning on or off can create pops that come into the equipment on the AC line. IME, most so-called high end audio 'conditioners' are not really all that good at their job and may be unable to filter such events, or they could even cause them. Some preamps are more susceptible to this sort of thing so it is possible that the Cary is working fine but simply can't reject events like this. I see this hypothesis as unlikely since we'd have heard of it before on this forum... And of course the popping could be a failing power tube that is arcing. So it is worthwhile to do your due diligence. |
