The specifications, especially the DC coil resistance of the Fidelity
Research moving coil cartridge, FR MC202(discontinued).

Legendary Japanese maker of MC pickups in the 70's and early 80's,
while their pickups where price-wise more in line with the likes of
Supex and the European producers of pickups that with the high end "I
can't believe this price" Japanese ones like Koetsu or Myabi the
company still had a reputation second to none when it came to sound
quality of their higher end pickups. Amongst their models where the
low output FR1 also available in a MkII version around 1980 or so and
in a MkIII version a little later (the MKIII version appears to have
been a high output part however, or at the least available in a high
output version). The FR-7f cart was integrated into a headshell. The
MC 201 is another low output cart from the early 80's and there was an
improved version of it called MC 202 (or FR-202 ?), these models are
not as sought after as the FR-1 however so I assume that they where
cheaper and/or inferior or perhaps it's just a coincidence.

The technical specification of the FR1 MkII are : Frequency response:
20Hz~20Khz. Output: 0,1 mV. Tracking force: 1,5 to 2 grams. Channel
separation: 27dB or better. Weight: 10,5 grams. Load Impedance: 30
ohms.

The technical specification of the FR1 MkIII are : Frequency response:
20Hz~20Khz +0.5dB -0db 20KHz~45KHZ +5dB -4dB. Output: 5 mV. Tracking
force: 2 grams. Channel separation: 27dB or better at 1 to 20KHz and
-18db at 30KHz. Channel balance: Less than +-1dB @ 1KHz. Compliance:
10 x 10-6 cm/dyne. Weight: 10 grams. Load Impedance: 10 ohms .

Thanks very much Harrold. I specifically need the DC coil resistance
because I recently purchased a Jeff Rowland Cadence phono stage and I
need to match it with the FR MC202. Thank you again for your comment
