  • The Edison Bell all-mains radio-gramophone can be run off A.C. or D.C. mains and is equipped with a moving-coil speaker, electric motor, and specially designed pick-up.

    When the instrument is required for D.C. mains a rotary converter is supplied with a special smoothing circuit, the whole being enclosed in a separate cabinet so that it may be placed at any distance from the radio-gramophone.
