Elartford,
Google first, ask second should have been my course.
Seems that Micro-Accoustics was making truly high end ceramics up until 1984 (well, high end back then)- with their top-of-line 830CSA Electret @ 10Hz-30kHz +/- 0.75dB freq. response and tracking at an amazing low mass of 0.75 to 1.25 grams with beryllium cantilever - $335.00
These Electret line of ceramic carts came with an internal micro-circuit to convert amplitude and reduce piezo velocity (the non-magnetic transducer material that made ceramics do their thing - made of lead-zarchonium titanate) so that output could be taken to the more prevalent MM input stage. Dang! Thought I could bypass a phono stage altogether.
