I am happy to report that sound_speaker_repair is selling some REALLY good diaphagms for your UHF drivers. I just installed some in my last pair of 076's and after putting them through their paces, am HAPPY with the results! I know there are probably some differences but in the A+B+C tests, my ear cannot distinguish a difference AT ALL. Not bad for $78.00 for the PAIR! They are on eBay and usually have BUY IT NOW's so you don't have to wait and FREE shipping to boot. These diaphagms are aluminum w/kapton formers and edgewound voicecoils. So, if you want or need new diaphragms and don't want to break the bank, give them a try, you will not be disappointed.
