• Notes

• Sharp Model BX330

  A new transistor dual wave portable. Employing 10 transistors, one germanium diode and thermistor, the BX330 operates from 4 x 1.5V (C Cells) flashlight batteries.

  Uni-stage RF amplification circuit gives clearer shortwave reception and easier shortwave reception is achieved by means of a highly sensitive built-in ferrite core antenna. Radicator gives accurate tuning and slide dial makes selection of station and tuning easy. Earphone, external antenna and leather case are included. (FROM MINGAY'S PRICE SERVICE)

  Frequency Range:
  BC 535~1605 kHz
  SW 3.9~12 MHz.

  AC Adaptor and External Antenna jack, High and Low Tone selector. Output 200 mW.
