  • Monodial AC Super

    An ultra-selective superheterodyne giving high-quality reproduction. Employing a combination of selective tuning and tone correction on the Stenode principle the selectivity is such that any stations separated by 5 k/c can be received without modulation interference.

    Designed by W.T. Cocking and presented in Wireless World on April 13th, 1932.

    Features of the Set.

    • Single-dial, eight-valve AC superheterodyne with variable-mu HF and IF stages.
    • Screen grid 1st  detector, triodes for the oscillator, 2nd  detector, tone corrector, and output stage.
    • Special band-pass filters with a total of eight tuned circuits and one stage of tone correction allow high note reproduction up to 5,000 cycles with extremely high selectivity.
    • Volume control acting simultaneously on the grid bias of both variable-mu valves with an additional local-distance switch.
    • Free field current for moving-coil speaker.
    • Undistorted power output 2,500 milliwatts.
    • Special oscillator tracking arrangements simplify the ganging of the oscillator and pre-selector circuits and secure freedom from second-channel interference.

    Approximate cost of parts, excluding valves, 17 gns.

  • Precio durante el primer año
  • 17.00 GNS
