  • Notes
  • This model shows a sticker with the following text about brand and manufacturer: "Made in Canada for the Victor Talking Machine Co. of Canada Limited. By the Northern Electric Co. Limited. Style R24, Serial M-19121. Patented 1918, 1922, 1923 & 1924." There is no dash between R and 24. The tiny tubes R215A are made also by Northern Electric Co. Ltd. The cabinet is made of American Walnut. The model has Radiola III style coils. This is the first model of Northern Electric which does not display the tubes through holes in the front panel.

    In the book "The early development of radio in Canada, 1901-1930", Robert P. Murray writes the following for that time:
    "On April 23, 1925, NE reached an agreement with the Victor Talking Machine Company of Canada Limited in Montreal. They began production of a series of receivers to which NE apparently contributed the chassis and Victor the cabinet. ... The first of these Victor/Northern electric models was the R-20 ... using two R-215-A tubes ... was much like the R-12." Then came R21 with three R215A tubes and R22 as R21 with a horizontal radio panel in a Victrola gramophone cabinet - and an upright Victrola was labeled type R23. Afte R24 followed in 1925 a type R30, a typical "three dialer" with 5 of the R2321DX tubes (functionally equal to UX201A). "After 1926, NE and Victor appear to have gone their separate ways." Victor made first its own receivers and then later presented models under the RCA Victor name.
