Rare find -- a brand new in the box, unused Fidelity Research FR-1MK3F low output moving coil phono cartridge. Superb sounding cartridge -- I own three of them -- so this one has sat unused. I'm getting out of analog (see my other ads). Why buy a used cartridge with a sketchy estimate of hours on it when you can buy brand new?
The most advanced cartridge in the FR-1 series, the FR-1Mk3F was the first MC cartridge in the world to use pure silver wire for the coils.
As a conductor, pure silver has lower resistance than any other metal. Therefore, efficiency is greatly improved without the need to make any other alterations in cartridge design. Mobile Fidelity Sound Lab (MFSL) used the FR-64s / B-60 / FR-1Mk3F combination in the former times for Playback.
Coreless coil to prevent hysteresis distortion, extremely durable suspension, this "F" version is shockingly superior to a lot of modern cartridges. When the Phonstage can handle the output, a superior cartridge for any Linear tracking tonearm, too. Updated Diamond & Cantilever from a Japanese Master greatly improving high-range response.

Paypal adds 4%, buyer pays shipping, which shouldn't be more than $10 via USPS Priority Mail. Local Los Angeles pickup is acceptable as well. No trades. Thanks for looking, and check out my other ads. I have plenty other analog-related items available, please inquire if interested.
