  • Notes
  • The Sparton model 86-X receives the following bands: Broadcast 550 - 1500 kHz and the SW bands 1.4 - 3.4 MHz, 3.3 - 8 MHz and 7.5 - 19 MHz. Rider's shows the same schematic for models 80, 83, 84, 85-X and 86-X. Since it has the same chassis as model 80 without VisoGlo we presume that this has also none.
    See the article here about season 1934/35.
