Tube Whine noise...Please Help

I had the same issue (same tubes)-John suggested reseating the tubes--it worked.

Hi Orind, by reseating them, do you mean removing the tubes & reinstalling them?

Jig is pulling your leg. ALL tubes operate on the principle of "thermionic emissions". Without thermionic emission the cathode would emit no electrons and the tube would just be a pretty piece of glass. The noise you are experiencing is oscillation or "feedback" caused by the physical elements inside the tube being too suseptable to external vibrations. BWT, RCA did not manufacture a 6922; they relabled. If it says "made in germany" odds are it is a Siemens. Holland or USA likely Amperex.

Yes. You can always call John at Musical Concepts if you have questions.

My expirience with the Emotive Audio Sira LE is same. I switch to the Tung Sol 5687 and got some microphonic noise, especially when touching the volume or the preamp. Well, I like the sound of the Tung Sol 5687 better so the "ring" thing doesn't matter to me. When the music plays, that's what's count.
