  • Notes

  • The Sears Silvertone 1936 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 1996.

    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

    Catalog states: Valuable New Weather Band - Gets reports from govenment stations. Greatly improved Foreign Reception - Gets stations from Europe, South America, also Police and Airplanes.  Coast to coast American reception. Two Speed Tuning Control and Micro-Tuning Hand - Makes Foreign stations as easy to tune as American stations. A great help for re-locating stations.  Two tuning ratios, 17 to 1 and 80 to 1.  New Flash-O-Lite Dial - Beautiful Airplane type with light that flashes on only when dialing.  Goes out when knob is released.  Saves battery energy. Full-Range, 10-inch Dynamic Speaker - Assures highest fidelity.  Tilt-Up Tone Chamber - Lifts tones to ear level, away from floor.  Automatic Volume Control - Reduces fading and blasting.  Full-Range Personal Tone Control - Emphasizes high or low tones, as you desire.
