  • Notes

  • The Sears Silvertone 1760 is an AC operated 8 tube BC and SW band receiver. 

    Chassis using this circuit are rubber stamped 206A or 206B. 

    This model originally had problems with hum, and minor changes were made by changing the values of C16, R9, R10 and R11 per the notes listed in both the Sears Service Manual and the Riders manual.  The production release of this model with the changes incorporated had the chassis stamped 206A or 206B.  The original production release without these changes had the chassis rubber stamped 206.

    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).
