Radios built during World War II often have unusual tube line-ups, usually due to shortages. This one is no exception. Being basically an All American Five, instead of the ubiquitous 12SQ7 tube, they used the older double-ended equivalent 12Q7. As well, instead of the more usual 50L6 audio output tube, they used a 35L6 with a series resistor in the heater string.
This radio came to me for a total restoration, including refinishing of the cabinet which was fairly rough, needing lots of glue & clamp repairs. The chassis was very dirty, and the cabinet interior was surrounded with asbestos, which was carefully removed and discarded.
Electronic restoration was routine, except for one unusual snag. I could not peak one side of one of the intermediate frequency transformers. It turned out that the internal shunt capacitor had a poor electrical connection to the coil it was in parallel with. Re-soldering the connection solved the problem.
Total restoration time: 21 hours
