Resonance From Dt25 Valves

Is this a plate rattle? maybe...If so, you might can verify it better with a pencil...tap each tube with a pencil, if you hear it...you have some microphonics and you need new tubes...if the amp is less than 90 days, I think Line 6 has a 90 day warranty on the tubes...

I am getting a similar problem with my spider valve when I play a B maj chord. I hit the chord, then mute the guitar and a resonance note at 192Hz just sings out and wont go away until I turn the standby off. Very annoying as I start in a new band next week.
I can send a sound file if need be.
