Tubes rattles like a bee

[Adambomb]

Seems like the tube rattle in my Dual Recto 3 ch is getting worse. It's a little bee like rattle and it's driving me nuts. Gets worse as I turn the amp up.
What can I do about this?

Replace your preamp tubes. They shouldn't rattle. Send it to MESA, they may throw some new tubes while they're fixing your gain issue!
