  • Notes
  • This Sears Silvertone 7004 is the superhet with the new chassis made by Sentinel Radio instead of Colonial, with the knobs in a straight line. See details and summaries about Sears catalogs etc. Don't confuse with this Silvertone 7004 in several versions a few years later.

    The Sears book "Service information 1928 thru 1936" shows on page 184 the same schematic for the models 1320, 1324, 1326X, 1386, 1454, 1456, 1531 and 7004. See this special text about first Silvertone superhets. Some of these Silvertone radios (1320, 1324, 1326) were available with an earlier chassis with knobs arranged in a "v" (triangle, top down) with 3 tubes 35.
