• Notes

• For model 5-26, Sparks-Withington made a cabinet version (table model) and a Consolette version. 
  We are not yet sure if this is really a 5-26 Console (instead of Consolette) and we don't know if this was also available with two tuning knobs instead of three. The cabinet is also different to the other Sparton consoles. When we know that this is in fact a 5-26 Console, then we have to change also the texts of the models linked below.
  The early version has THREE primary tuning knobs, but soon they have ganged two capacitors together - and those models offer TWO tuning knobs. Pictures should be according: table model 3 tuning knobs, table model 3 tuning knobs, Consolette 3 tuning knobs, Consolette 2 tuning knobs. All versions of model 5-26 have three scales! Lift top and fold down front, upper center shows the sparton logo.
  By removing wire jumpers, the radio can accomodate a power tube 112A - or later the 171A, with additional bias voltage and higher anode voltages (135 or 180 volts). The list "The quantity and types of tubes used in Sparton receiving sets" from 1937 or later names the tubes 01A which are much later dome shaped tubes, not the original tube line up! Original is: C-201A C-201A C-201A C-201A C-201A or C-112A.
