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 used 4 small clear rubber pads (one sticked in each corner) got them at the 1$ store.

I don't think it is wishful thinking - it is real. Especially when enjoying a long session at a good volume level.
