Vintage 1940s ZENITH “LONG DISTANCE” TUBE RADIO No. Tested and in working condition. These radios are early postwar Zenith portables with loctal tubes and use Zenith “Wavemagnet” antennas that have several tubes, including the 1LA6 converter, a loctal version of the 1L6 (then considered more expensive). The wavemagnet in these models has an interesting art deco design on the back side. That side would be visible to the outside world if the antenna were to be used with suction cups on a window. Chassis number on this 6G001Y is 6C40, serial number T980025. The speaker is stamped with 49U512 assumed to be a date code. A schematic can be found in Rider volume 15, Zenith pages 30-31. These may be downloaded from Nostalgiaair. See the home page for the Nostalgiaair URL. It is highly recommended to test the circuitry with an ohmmeter before applying power. The set can be cleaned with white waterless hand cleaner. The cover material is relatively easy to clean. A coat of old-fashioned black carnauba wax shoe polish can help restore some of the luster. Contact cleaner can be used on the tube pins and sockets.
