  • 3 Valve Long Distance Receiver in Oak Cabinet

    The receiver's full operational spectrum spanned 250 to 2000 Metres (150 – 1200 kHz). 

    • Tuning Coils: The system incorporated six interchangeable plug-in coils to broadly select the desired frequency band.
    • HF Transformers: Fine-tuning and efficiency were optimised across specific segments by employing a selection of different High-Frequency transformers, specifically wound for the 300m (1000 kHz), 600m (500 kHz), and 1250m (240 kHz) bands.

    Sold with 300ft. Aerial wire, 6 insulators, 1 lead in tube.
    12ft. V.I.R. wire, 1 pair of Brandes or Siemens headphones, 3 DE3 valves, 1 36 V HT battery, 2 LT cells, 6 plug-in coils, 3 HF transformers.

    Cash £28-0-9

    The RRA is especially suitable for long-distance reception; its arrangement of radio-frequency tuning is ideal for clear results.

    On good aerials, the Eastern stations will come in well on Headphones. For long-distance loudspeaker reception, the 5-valve Combination Cabinet type RRD AA is recommended.
