Model 31W isn't listed in Rider. Use the schematic for 62-040, Commodore or 62-181, Sovereign which use the same tubes. The schematic is available here on nostalgiaair.
: I have a Montgomery Ward Airline console radio using a tube complement of 1-280,2-245, 3-224 and 2-227 tubes with a chassis number of 31W.
: am looking for a schematic.
: Thanks
