Electret indeed. Just goes to show that there is more than one way to skin a cat, or to produce a cartridge. Sort of strange that MCs get all the attention and are so well represented within the "survivor" ranks of cartridgedom. Now if someone could explain how an electret works, that would be fine, beacuse all I can remember is that the change in the material itself brought about by the mechanical action of the stylus attached to the electret material alters electrical current, or something like that. In a way audio was more fun back then. Remember the Empire 2000Z? That was also confused with a moving magnet and, though quite similar, was actually a moving iron cartridge, if memory serves me right. Does were the days!
