moving coil loading
I'm getting back into my audiophile hobby and dusting off my vintage gear. I have a question on the preamp loading impedance my Fidelity Research MC-201 cartridge. The specs for the cartridge are:
Stylus: 0.3 x 2mil line-contact solid diamond stylus
Output voltage: 0.16mV
Coil impedance: 8 ohms
Load impedance: 10 ohms
My Acoustat Trans nova preamp allows me to install any resisters required for loading the MC circuit. Just not sure on what value resistors to use. Any guidance would be appreciated. If more information is needed let me know

Wow so much info, making my head spin. I was going to try copy and paste pages 4+5 from the manual which discusses mc loading, but if you follow the link above you can look at it directly. I just sent the preamp out to be checked out and potentially upgraded, that's why I wanted to research the loading issue and figured this is the best time to get it right. I do appreciate all the comments and help |
The preamp only supply 6 sets of loading resistors, that is the reason I recommend the metal film resistor kit, it contains 1280 pieces 64-value ±1% metal film resistors for $10. My suggestion is start with 82Ω or 100Ω, and try different values to find what sounds best to you.
