This module was used in the Dolby 330 and 334, both Dolby B noise reduction units, one for cassette tape duplication and the other for FM broadcast noise reduction. I've found an owner's manual, online, for the 334 however the original scan was fairly low resolution and the original poster no longer has the manual. I've contacted Dolby Labs but they don't seem to support their older products very well.
Any information would be much appreciated.
