  • Notes
  • This model line Olympic 6-604 with built-in loop antenna consists of 6-604W-110, 6-604W-150, 6-604W-220, 6-604V-110 and 6-604V-220, each in a version "early" and "late" with an other tube line up. The suffix indivates the AC/DC voltage: 110 = for 105-125 volts, 150 = for 140-160 and 220 = for 200-240 volts. The suffix W stands for color Walnut and V for color Ivory.

    Rider's documents the same range of models as SAMS, but on pages 17-1 to 17-2 for the "early" version with 12SK7 etc., followed by information about "early" and "late" on page 17-3 to 17-4, followed by the documentation of the "late" model range on page 17-5 and 17-6 with 12BA6 etc.

    SAMS Photofact set 22 of date August 1947, folder 4712-21 is for the "late" model line with tubes beginning with 12BA6 etc. instead of the 12SK7 of the "early" model line - again for all 5 versions. Beitman 1947 documents the "early" version on one page for models 6-604W and 6-604V.
