i have 3 knobs in the back which to my understanding they are volumes? or really sound shaper? could they be bypassed ? or better off leaving them , what about the fuse any gain putting a better one? its in the signal path right? if you changed it what brand would you suggest? thx !!!

hi everyone! i recently bought a pair of totally refurbished woofer ,tweeter and xover Carver Amazing Platinum 4 ! i had a question concerning the screws that are on the tweeter close to the magnets (the magnets are reglued also), had a slight buzz on piano notes while playing a little louder than moderate volume. i noticed i had a few of these screws were loose, i slightly tighten them and the buzz went away 80-90%. but i have no idea what they are holding so i dont want to kink the metal in the back or damage something inside. is there a torque number as a reference? any help is appreciated. other than that its an ''amazing'' speaker :) my friend who had a pair but weren't all refurbished felt they sounded lifeless, but now he want's to trade his Mirage M-1 for mine
