I read where someone suggested the back to a dual socket connector had asbestos. I thought it was a heavy cardboard or fiberboard. I tried to research it and didn't find anything on that but someone was stating the white circles in the foot controller that go around the screws and are between the ceremic and the bakelite are asbestos. He claimed he replaced them with insulating phenolic washers. So what do you think? Should we be replacing washers? Is there a reason to be concerned?
