Notes

Basically the same radio as BX760X but the BX760A can not be converted for DC mains. See the technical documents uploaded with this model for all the differences.

AM radio for external antenna:

  • LW: 150 - 424 kHz.
  • BC: 536 - 1714 kHz.
  • SW1: 5,94 - 9,8 MHz (30,4m - 51m with bandspread at 41m and 49m).
  • SW2: 9,5 - 15,46 MHz (19,4m - 31,6m with bandspread at 25m and 31m).
  • SW3: 15,07 - 22,55 MHz (13,3m - 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.

Amplifier: Class AB push-pull with (contrast-) expander and signal limiter to avoid clipping at maximum output power. Also physiological volume control (loudness) and sound quality selector with 5 positions or presets (equiliser).

Loudspeaker: 9634-05 or 9734-05 (both 7Ω, 23.5 cm, with soundwave diffuser).

Dial lamps: 2x 8045D (E10, 6.3V/320mA).
