This is a nine tube radio...and it produces a It is extremely heavy, around 90 pounds. |

| Operation: Installation of this radio includes erecting a long ariel antenna and a copper pipe driven into the ground for a "Ground" connection. It plugs into a regular 120 volt receptacle. The owner would turn the toggle switch "up" to "on", which is located on the Right side of the radio near the top. After a minute or so the tubes would warm up and static or a station would be heard. The front Right knob adjusts the tuning..and a cool looking illuminated rotating dial behind the center window. The tuning scale displays the station in the familiar frequency. The volume control is the front Left knob, and if the signal is too weak the front center knob might be switched to "local". If the station is too loud and distorted it might be in the "Distant" rotary position. |

Logical order of repair is: |
|||||
Since the cabinet is first in line, all components were removed and the wood was cleaned with oil soap, fine steel wool and lots of rags. |
|||||
The power supply/audio amplifier was refurbished next. We wanted the power supply to end up being bright shiny metal, but would mean removing the capacitors and transformers from the top for polishing. The speaker cone was missing 1/4 of it's cone as seen in this original picture, and was repaired using a combination of glue, masking tape, paper and paint. Probably not the best speaker repair in the world but I doubt it will do much "Thumping" anyway. Since the main filter capacitor showed signs of leakage we replaced it with new ones mounted between two new terminal strips. |
|||||
Next we tackled the radio chassis. This time we removed all components from the top: tubes, shields, tuning capacitor assembly etc and cleaned the chassis to a bright shine. Several coats of furniture wax will keep it from corrosion for a very, very long time. The tube shielding couldn't be cleaned as easily so we settled for black hi-temperature paint. The massive tuning capacitor was disassembled similar to our Stewart-Warner pictured here, cleaned and reassembled. Today the radio and chassis is completely cleaned up and have been powered up without any unpleasant surprises. The radio does not work, and we are in the process of troubleshooting and repair. |
