Aeolian Tracking System Vacuum Supply
By Dan Harrett

Has anyone developed a tubing diagram for the tracking system in
a Themodist Metrostyle player with two-ear tracking?

Julian Dyer advised me that there are _two_ vacuum supplies for it,
one continuous and one below the action cutoff.  The fine Themodist
tubing diagram done by Richard Vance in the MMD Archives shows
a single ear tracking system.
