@roial1's QSC's had a loud rattle when the bass hit. When disassembling, one screw kept spinning. Easiest troubleshoot ever. Mixed up some 2-part epoxy and it's as good as new. #QSCRepair #QSC #turntableteknicianz Leave a reply Share this:Click to share on Twitter (Opens in new window)Click to share on Facebook (Opens in new window)
