I want to clean my old Shure545 (it's the late 1960 or early 70s version), but I can't unscrew the top. I can't find instructions online how to open it, and they guy who sold it to me said the foam inside can't be replaced because it can't be opened. This seems a bit crazy. Does anyone know if it's true and/or how to open one?
