Beschreibung:
The Electrical Experimenter, August 1916. Volume 4 Number 4.
Advertisement for electric Columbia phonograph.
Notes: Electric power was for spinning the turntable (instead of more common hand-cranked clockwork motors); reproduction of sound was still strictly acoustic. Power cord shown screws into light socket, rather than wall plug.
The page numbers were on an annual base, not per issue. This issue had pages 225 to 304. Page 302 is shown.
