  • Anotaciones

  • The Sears Silvertone 1996 is a DC operated 9 tube Longwave, BC, Police and SW band receiver. Uses 1F1 ballast tube to reduce the 3V filament supply to 2V.  Has AVC, Qty(2) IF stages and push-pull output stage.  Uses Qty(2) 1.5V flashlight batteries to power the dial lamp, which is lite only when knob is pressed. Uses the first +22.5V tap from the B+ batteries block as a C+ battery, thus the actual B+ voltage is 167.5V.

    Chassis and schematic used in this model also used in model 1936.

    Band Frequency Ranges are as follows:
    LW Band (Band A).............220-400kHz (Weather band)
    BC Band (Band B).............540-1700kHz
    Police Band (Band C)........1.67-5.25MHz
    SW Band (Band D)............4.25-15.5MHz

    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).

    The "Late" model uses a 951 detector tube instead of the 232 tube used in the "Early" model.
