  • Columbus Model 66T

    6-Valve superhet with RF stage dual wave table radiogram.

    See also Columbus 66R variant which is likely to have a similar valve lineup.

    The number of Model 66 variants was due in part because of wartime component shortages plus the long model run 1941-1949.  

    Manufactured by Radio Corporation Of New Zealand Ltd for Columbus Radio Centre Ltd.
