My experience is that I had a high pitched ringing or a vibration like hum. This was alleviated initially by cooling and reinstalling the tubes. As the tube aged they got worse and we’re replaced. The 2 times I experienced a single pop, it was t preceding a tube failure , but with power tubes. Once the glass envelope failed with a poof and I shut it down. The second was a violent pop that resulted in a blown capacitor and resistor that required Mr Had to repair my amp. That one involved a brand new Gold Lion that he said failed and caused the damage. Good luck with your issue.
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 “. 😆 |
