  • Notes
    • This superheterodyne radio works on a simple wire antenna, where previous SBR superheterodyne models worked with a loop antenna.
    • Tuning scales with names and wavelenghts are standard from now on.
    • In the 110V DC version there are 2 output pentodes in parallel to compensate for the lower plate voltage, in the 220V DC version there is only 1 output pentode.
    • The turntable is either SBR or Marconiphone.
    • The ballast tube is only for the filaments; the tubes are working on a higher plate voltage than the 110V DC version.
    • SBR produced the following models 533:
      • 533x1: table model without loudspeaker;
      • 533x2: table model with loudspeaker;
      • 533x3: luxury console;
      • 533x4: luxury console with pick-up;

    where 'x' represents 'A' (AC mains) or 'C' (DC mains, 110 or 220V)

    • The "251_Ballast" current regulator (250mA; 60-180volt) can be replaced by any other brand of current regulator with the same or better specifications and the same foot (B4), like the Marconi "251_MOV" or the Philips "1934".
