Purpose of Coil and Capacitor SME III Tonearm


Does anyone know the theory and practice of the coil and capacitor hooked to the grounding of a SME Series III tonearm? Is this a filter for the tonearm ground? If so, how does it work? Are there any similar designs in other tonearms? I have only taken apart Thorens arms in the past and these don't have this set up.

Thanks

Don't know too much about your tonearm, but a coil and capacitor usually are low/high pass (frequency) filters. A series capacitor and parallel coil pass high frequencies. Conversly, a series coil and parallel capacitor pass low frequencies. These are also the basics of speaker crossovers.
