Try looking up a firm called Micro Acoustics !! They produced two cartridges!!
Ma 2002 and Ma 530 BOTH are electret condenser carts, with power for the condenser derived from the signal itself. BOTH of these carts used thinwall Beryllium tube!!!! They were wonderful carts and were at least equal to the Shure. They could track down to half a gram WITHOUT mistracking.
I owned both in the early 80's, and were used on a Micro Seiki DD20 turntable, which also had an arm at LEAST the equal of an SME 3009. Tracking could be adjusted while playing a record. with a precision spring inside the arm tube, and connected to the adjustment knob by a very fine tungsten wire. It did have a counterweight, but that was purely for neutralising the weight of any cartridge fitted.
