	    3-piece EDISON "Voicewriter" Wax Cylinder
        	Recording/Playback/Shaving System

The complete EDIPHONE office set, as was employed in state-of-the-art law
offices in the late 1930's including 8 original Edison wax recording
cylinders, most with hairline cracks but still usable in original
soft-lined cartons. Recording unit comes with the original ceramic
microphone (functionally restored) as shown and has a vacuum tube audio
amplifier built-in to the unit which drives a ceramic recording stylus
which etches the wax cylinder. The playback unit is similar to the
recording unit except that it has a playback stylus and a mechanical
sounding diaphragm to which a horn or earphone (not  included) is
connected. The cylinder shaver ("Master Shaver") is used to shave the
surface of used or damaged cylinders in order to make them rewriteable. It
functions like a small lathe. All three units feature very sturdy
heavy-duty construction and have easy and intuitive stainless steel
ergonomic controls which are characteristic of early shop equipment.
Fractional horsepower Edison universal AC-DC electric motors are employed
in all three units and all motors were cleaned and lubricated three years
ago. The recording and playback units use adjustable flyball governors
which stabilize the rotational speed of the cylinders. Fine pitch worm
drives are used in each unit for steady stylus tracking. All three units
can be brought to working order after the following repairs are performed:
the paper sounding diaphragm on the playback unit is torn and should be
replaced or rebuilt; the ceramic stylus on the recording unit is also
internally damaged and needs to be replaced; the shaver needs a new
shaving bit (which was originally a sliver of glass). All three units have
the original paint and silkscreening which show signs of age.
