    AM radio for external antenna:

    • LW: 150 - 423 kHz.
    • BC: 545 - 1750 kHz.
    • SW1: 5,8 - 9,8 MHz (30,6m - 51,2m with bandspread at 40m and 50m).
    • SW2: 9,5 - 15,4 MHz (19,4m - 31,6m with bandspread at 25m and 30m).
    • SW3: 15 - 23 MHz (13m - 20m with bandspread at 16m and 20m).
    The radio contains a 6-section variable capacitor from which 3 sections are used for the LW and BC band, the 3 other sections are used for the shortwave bands. These shortwave sections have each 2 large gaps in every plate to permit a slower change in capacitance when turned in, thus effectively stretching the tuning scale in those areas. See the technical documents uploaded with this model (in Dutch).
     
    A selenium diode is used in the AVC circuitry.
     
    Loudspeaker: 9702-05 (7Ω, with soundwave diffuser).
    Dial lamp: 2x 8045D (E10, 6.3V/320mA).
     
    The radio can also be used on DC mains when adapted with a unit 7882C vibrating converter.
