  • 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.

    This Model 48 was in the same style as the earlier “Empire State” Radiolettes but was designated Radiola on the badge where the previous models had been designated Radiolette.

    4 valve, superhet with an IF of 460 kHz.

    • The valve positions and power transformer location reorganised compared to the previous Model R37.
    • The tuning gang was mounted on rubber mounts and earthed with braid.
    • A "local-distance" switch at the rear of the chassis is provided for reducing overload in strong signal areas.
    • The chassis did not require the wooden plinth.

    This Model 48 was only available in Black with versions 48A in Figured Walnut, 48B in Grained Ivory and 48C in plain Ivory.

    The back cover was mounted with screws and made from the same material and colour as the cabinet.

    This Radiola’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.
