  • Annotazioni
  • Plate outside is for RCA Brunswick-Radiola Super-Heterodyne (Second Harmonic), licensed only to extent indicated in attached notice Supplied to "The Brunswick-Balke-Collender Co." by Radio Corporation of America. General Electric had to rework the chassis AR-812 (and AR-810 schematic), technically identical - but not so wide - to fit into the Brunswick-Balke-Collender models. A horn loudspeaker is built into the cabinet and the coil antenna sits in the door of this rare Brunswick model. RCA is only the brand (they did not manufacture radios at that time, but the parent companies like GE or Westinghouse). Only one IF transformer is tuned (by a condenser), therefore we count only 3 tuned circuits. The reception range is 220 - 550 meters. The patent list starts at January 21, 1903 and ends (with 18 patents) at June 18, 1923.
