  • Notes

  • The Sears Silvertone 7048 is an AC operated 5 tube BC band receiver.

    See details and summaries about Sears catalogs etc. This model was manufactured for Sears by an unknown company that was no longer in business when the Sears Silvertone Service Information Book was published in May 1936.  At that time, parts for this model were supplied by Wholesale Radio Service Co., New York City, NY (Sears Manufacturer Source Number Code 118).

    The schematic from the Sears Silvertone Service Information Book is the same as the schematic of the Clarion AC-320, which can be found in Riders 4-5 under Transformer Corp of America.  The alignment instructions are also listed in Riders 4-5, which can be used for this model.
