Does anyone on the list have any experience with the Cook Binaural System? Cook Labs of Stamford, CT issued some 33 1/3 12" LPs that have to be played on a twin tonearm turntable. The front of the album says "For use with the the 1-11/16" standard Cook system. Playback outside track - 12 db @ 10 kc. Playback inside track - flat. 500 cycle crossover both tracks."
I have 8 of these albums in front of me and am curious if anyone has knowledge of the extent (and dates) of the Cook binaural experiment and if anyone has ever seen the Cook turntable.
Thanks in advance,
