Need information on the Audio Technica AT6020 Cartridge Analyzer. A device I purchased used, mint. It is to setup any cartridge while playing a test disc. There are provisions to seperatly measure left /right voltage output, crosstalk etc. enabling precise VTA and Azimuth ajustments. Also resistive and capacitive loading with a ocilloscope output and much more. Any source or information would be greatly appreciated...RJN
