Hi Old Grey,
I did some checking, and it is not a commercial product. The motor was modified as well....I guess it shows it can be done. John Devore did use it at the show--his buddy Jonathan Halpern of Tone Imports plays some delightful 78's I'm told.
I always thought I'd like to try getting into 78's....maybe pick up a used Thorens was my idea....of course, one could always get Halpern's wonderful Shindo Garrard table...
