It is a six tube ac superhet tuning the standard Broadcast band, 550 khz to 1550 khz and two Short Wave bands, 1.6 to 5 mhz and 6 to 10 mhz. Radio looks awesome and is in great working condition. The model number of this gorgeous looking radio is 6S439 and was produced for the 1940 season.
Specially in this nicely restored condition. The cabinet is made of walnut and exotic veneers and is a reddish brown in color. This cabinet is striking in design with it's wrap around speaker grill and large metal escutcheon.
Also unique is the convex glass which covers the black slide rule dial. The Zenith logo is located top centered on the escutcheon. The cabinet had been recently stripped and then sprayed and top coated with clear lacquer.
The top of the radio was badly stained so it was. Sprayed dark walnut and then lacquer topcoated. The finish is close to the original look and the shine looks spectacular. This radio is extremely nice and for a radio that is 75 yrs old, it looks... I have taken many pictures so you may get a good look at this wonderful looking and working radio.The electronics were upgraded with all the old filter caps being replaced with a modern electrolytics. All the old wax paper coupling and by-pass capacitors were replaced with new high quality "orange drop" capacitors. All the resistors were checked and any out of tolerance were replaced. Any original wiring that was crumbling was either re-sleeved or when necessary a new wire was installed. A new polarized power cord was installed. The original Zenith power transformer was missing so a replacement was installed. The speaker is in great condition, no holes, tears or cuts. The original grill cloth was beyond saving so a new period cloth was installed. The dial cord was broken so a new cord was installed. All tubes were tested and all now test "good". And, finally the radio was aligned on all three bands. This radio has been restored to good working condition. He audio is pleasant and loud without hum. This radio had a very complex built-in loop antenna, which was in shambles. Most of the connecting wires had been yanked off, the back masonite board was smashed with missing pieces, but the actual loop antenna, wire screening, switches and labels were still useable. So, a new homemade back was made with necessary connecting dowels and hardware. And then, the loop antenna was re-assembled. I think you'll agree that the final result looks as good as the original. He two position tone hook pull switches are located on the front and pushing-in either the "bass" or "treble" causes a change in tone.
The push-buttons are the original and were cleaned and polished. The push-buttons work, however I tend to leave the alone.
There is a rectangular piece of white plastic just above the buttons. That piece has to be popped off carefully and then there is access to the slug screws to electrically set each push-button.Place the band switch to. "Auto" and then turn the corresponding screw. This screw changes the frequency of an oscillator coil setting in the desired station.
This works on the broadcast band only. New decals were also applied and correspond to the position of band selection switch, the one with the arrow. The round knob, on the same shaft, below the band switch is the tuning control. Off to the left is the on/off/volume control.
The large slide rule black dial has a small scratch on the bottom, not noticeable once behind the glass dial cover, but no missing digits. The very distinct black dial scale has a sliding vertical pointer which was sprayed white. Both dial lamps were open, so two new bulbs were installed. The SW1 band isn't popular today, but the SW2 band is. With just a short length of antenna wire connected to the "A" terminal on the rear during the daytime lots of foreign stations were heard.
Connecting a long outside wire antenna to the radio will enhanced Short Wave reception. This is a 75 year old vintage radio and must be handled and cared for carefully. So where you position this radio in your home can make a difference in your enjoyment.
Also because of the loop antenna being directional, you should turn the radio for best reception. This Zenith 6S439 radio would make an excellent addition to your radio collection or as a stand alone radio. It has great eye appeal!
