The receiver (acquired at a radio flea market) is housed in a wooden cabinet and covers three bands.
Tubes employed: 6D6, 6A7, 6D6, 75, 43 and 25Z5.
I have got hold of the schematic of model 6800, which matches the wiring of my model 6850S pretty well. However, there seem to be some major deviations. Who can help with more information on this radio (schematic, year of origin, meaning of the suffix S in the model identification [made in plant "S" ?], etc.) ?

Sentinel-front   Sentinel-back


Label at the bottom of the cabinet showing the model no. 6850S
