Mustang Guy, This is a great thread, nice work. I have ordered recone kits from Klipsch for two 1976 vintage square magnet K33's. After reading the thread twice I have a question. When did you remove the business cards from the voice coil? I can see them removed in your photos but not sure when to remove and how. My concern is having some of the epoxy glue get on the cards and not being able to get them out of the former. I'm not as steady with my fingers and hands as I once was.
