I am looking for the changeover and operating instructions for
a 15-1/2" ReginaPhone style 250.  This machine was a gift.  I have
the turntable and the tone arm with the reproducer.  I don't know the
correct way to keep the rollers on the hold-down arm from bouncing
along on the disc drive sprocket when using the turntable to play 78
RPM phono records.

The only thing I can think of is to remove the two screws and the
hold-down arm or get a blank disc that would hold the rollers up off
the sprocket.
