The S80 which would have been the First Series of Dual 80 in 1/2" form, was replaced with the S80A which flipped the Cover bolts threads because there where issues with the screws working themselves loose over time. I know some people have resolved the issue with Loctite and others have said the dealers will swap the old series for a New one.. YMMV
