  • Notes

  • AWA produced a series of Bakelite Empire State radios between 1934 and 1938.

    Radiolette models R28, R29, R30, R31, R31A, R32, R37, R37A, R37B, R37C & Radiola R48& R48G.

    Empire State was not the official AWA name for the classic Art Deco Bakelite Radiolette but due to their popularity among worldwide collectors they are now known colloquially as the AWA Radiolette, Empire State Series of radios.

    Chassis:
    5 valve, reflexed superhet with an IF of 175 kHz.
    The tuning capacitor frame is insulated from the chassis.
    A "local-distance" switch at the rear of the chassis is provided for reducing overload in strong signal areas.
    The chassis was the same as the earlier Models, 28 to 30. However, the change from a box around the RF/IF valves to separate valve shields occurred during this models production.

    CAUTION! Asbestos is used as a heat shield to line one side of the can holding the two B+ capacitors.

    Cabinet:
    This Model R31A, was only available in Figured Walnut with gold silk speaker cloth.

    This Radiolette’s Art Deco Bakelite cabinet design was modelled on the wooden version AWA  Radiolette, Model 27 except with a square dial. Earlier Air King in the US designed models along these lines in 1933 with the Skyscraper 52.
