Rega TT Dust Cover Vibration


I have a P25 and recently while playing LPs loud (not ear busting, just loud enough) I discovered that the dust cover was vibrating quite a bit - enough to impact the playback. Anyone else have this issue? Short of taking the cover off, is there a way to defeat this gremlin??

I use my dust cover for just that, when I'm through I just set it back on the table.
I used 4 small clear rubber pads (one sticked in each corner) got them at the 1$ store.
Leaving the cover on while playing records you essentially create a drum like structure, with drum like resonances. Just compare the difference sonically with the dust cover on and off. I never went back.
