  • Bemerkung

  • The Sears Silvertone 1586 has a "Micro-Vision Triple Scale Dial". This is a moving scale AND a moving pointer that move in opposite directions! The loudspeaker has a hum bucking coil. Has a 3-gang tuning condenser but no RF stage - and reduced number of IF circuits depending on schematic version (referred to as a "self-tuned" IF output transformer). The model 1586 could be ordered for 25 cycle line power without any additional cost. The Silvertone console 1587 and the cathedral 1585 share the same chassis / schematic - see list below. This model is a domestic version and the mains transformer has no taps. But there is also a "Universal transformer" for 40 to 60 cycle available with taps: 115, 130, 155 and 230 volts. 

    This model was manufactured for Sears by Colonial Radio Corp., Buffalo, NY (Sears Manufacturer Source Number Code 101). In fact it is the schematic of Colonial model 62. But within the same model family there were quite a few changes made which are explained in the original Sears documentation included with the schematics. Even the tubes could be different (see plan "B"). The schematics are officially for models 1580, 1582, 1584, 1585, 1586, 1588, 1589, 7100, but model 1587 is also part of this model family and there are possibly others.
