Hi all, does anybody know where to get an auto off switch, the one that
PPCo sold?  It's the type you use on any old upright player when you
add a vacuum pump.  It's simply a small block of wood with a button
on the front and a metal tongue on the back.  It mounts on top of the
spool box after you drill two holes where the button and the tongue go
through.

When the roll is finished playing you push the button to turn it on and
after it's done and rewinds the roll tab slaps the tongue to turn it
off.

Thanks,
John Brzozowski
