- Model: Sparton 85-XS - Sparks-Withington Co., Sparton
- Console with any shape - in general
The Sparton model 85-XS is an export model and 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 but the original schematic shows also this 85-XS and model 835. Since it has the same chassis as model 83 with VisoGlo we presume that this "higher" model has it too. There are two models 83, one with the VisoGlo tuning indicator and the other without but in principle the same chassis. VisoGlo tuning indicator VG-1 is extremely rare, even in the literature it is nearly not noticed.
