- Notes
- The Silvertone model 4499 is the same as model 4498 but this model 4499 uses a 4 volt storage battery and the model 4498 uses dry batteries only. For details see schematic. It tells us that it has a "magnetic" speaker with approximate 1000 ohms DC resistance, but the Sears catalog tells us "It has a 6-inch Permanent Magnet-Dynamic Speaker, Ball Bearing Condenser, Automatic Volume Control, Personal Tone control." The schematic tells us as frequency range broadcast 540 - 1750 kHz.
