  • Notes

  • The Silvertone model 8021 from Sears, Roebuck & Co. with chassis 132.686 had been changed in the schematic (Resistors R20 = now 33 kohms instead of 100 k, added R28 100 kohms and R29 15 ohms) to improve the FM tuning characteristics. There were complaints of poor tuning characteristics. The model has a Diode Rectifier and a loop antenna. The Photofact date 9-49, 4918-10, set 70, folder 10 shows the schematic without revision. See the other model page "Revised".
