Hi, I saw your post about Carver ribbons and wanted to respond. If you have any questions you can get info by e-mailing to - Dave@carveraudio.com He is very knowledgeable about them and is also the only Carver authorized person in the U.S.(world?) to repair the ribbons. I talked with him by phone for an hour one day about repairing my ribbons. He is very friendly and will answer all of your questions. Hope this info. is helpful. Brent Busch
