Latest acquisition and restoration as of March 2018, this WWII radio was a tough one to get operational. A lot of modifications had been done to this radio, so schematics were basically worthless. Re-capped the entire unit, and figured out the modifications and finally got it working.
This radio was designed for entertaining and maintaining the morale of troops during WWII. This radio set was designed to be run either off of batteries, or 110 line voltage. Troops in hospitals, rear echelon areas, or barracks could tune in and listen to news, and music, and they were called “Morale” radios.
Provides for reception of voice-modulated signals in the broadcast band 0.54-1.5 MHz (AM Radio)
and additionally, two HF bands 3.6-8.5 MHz and 8.5-19 MHz. (Shortwave Radio)
