Notes The Colonial model 62 schematic and chassis was used for the Sears Silvertone models, officially 1580, 1582, 1584, 1585, 1586, 1588, 1589, 7100, but there is at least also 1587. But within the same models there were quite some changes made which are explained in the original plans we show for those models. Even tubes could be different (see plan "B"). Sears calls the dial with the moving scale AND pointer "Micro-Vision Triple Scale Dial". 3-gang tuning condenser but no RF stage - and reduced IF circuits depending on schematic version. The loudspeaker has a hum bucking coil.
The knobs are: top left is "Volume", below left is "3 tap Band Switch", center "Station Selector", top right is "Tone" and below right is the "ON-OFF Switch". The Silvertone models could be ordered for 25 cycle line power without any additional cost. It is a domestic version and the mains transformer has no taps. But there is also a "Universal transformer" for 40 to 60 cycle possible with taps: 115, 130, 155 and 230 volts.
