This is the legendary Fidelity Research FR-1 MK2 designed by Ikeda. This superb sounding cartridge was made even better with upgrades; it has teak wood side panels, has been cryo treated, and has a new Soundsmith elliptical retip. The third photo shows the classic Soundsmith box and blue tape before I took it out to make sure all was well. NOTE: this is a very low output cartridge- make sure your phono preamp has enough output!MOVING COIL Frequency response: 20Hz~20KHz +0.5dB -0db Channel Balance: within 1dB Compliance: 12 X 10-6 cm/dyne Output: 0.1mV Impedance: 30 ohms Tracking Force: 1.5-2.0 grams Cartridge weight 10 grams
