Here is an indicator for testing starwheel shafts to
see if they are sprung. It should be set on the
face of the sprocket and needle ride in "center" if
shaft is "true." Can also be used to check end-play
of
sprocket.
fective gear, shaft or coupling can cause
plenty of trouble and may cause considerable
damage to your projector drive. Check
the Allen screws monthly, and tighten if
necessary.
Photo-electric cells are very delicate but
will give long service with proper care. The
efficiency of the cell decreases with age
resulting in a gradual decrease in output
volume and frequency response. Always replace
cells before the quality of your sound
is impaired. P.E. cells should always be
firm in their sockets and contact should
be firmly made when replacing with new
cells. Correct voltage is of utmost importance
at all times.
