  • The Sears Silvertone 7103 is an AC operated 10 tube BC band receiver.  Has push-pull output stage with parallel 45 type tubes on each side for a total of Qty(4) output tubes.

    The chassis and schematic used in this model is also used in models 1720, 1725, 7065 and 7115. Riders Sears 4-22, 23; 5-13;7-15 schematics are for model 1720 but Sears Silvertone Service Manual 1928 thru 1936 confirms that models 1720 and 7103 use the same schematics, thus Riders schematics are valid for this model.

    See details and summaries about Sears catalogs etc. This model was manufactured for Sears by Colonial Radio Corp., Buffalo, NY (Sears Manufacturer Source Number Code 101).
