I recently got an unused M81MC phono cartridge but no spec sheet. What is the tracking force for this cartridge? How old is it? Any info or specs?
M81MC: >15 years old.
Original stylus: N75C; Spherical tip (0.6 mils); 3 to 5 tracking range
Available replacement stylus: N75B Type 2; Spherical tip (0.6 mils); 1.5 to 3 tracking range
No more information is available.
