Hey everyone, just curious if anyone has any solutions to this problem that has seemed to plague my theatre. Our Source Four ellipsoidal bases are constantly corroding/oxidizing and we've tried a thousand and a half ways to fix them. The only solution we've found that works is replacing the contacts, but unfortunately, this gets expensive fast. We've also just brushed out the contacts with wire brushes, but they only work briefly before going back to the original problem. We aren't sure why they keep dying, but it's killing our inventory. Anyone else had this problem? Or a solution?
