Made during the time of early FM radio, note there are two FM scales - 100 & 45. It sounds great too, with seven tubes, a 7.5 inch speaker and high/low tone control for your listening preference.It has excellent sensitivity and selectivity using the internal loop antenna. As with all of the radios I restore, it has been gone over with the utmost attention to detail. The cabinet was completely disassembled, thoroughly cleaned, then polished to a smooth and lustrous finish.
There are no scratches nor damage on the cabinet. It now looks as if brand new. The original knobs and controls were polished.The dial face graphics are crisp and clear, being uniquely lighted from the bright pilot light. The speaker grill cloth and power cord are replacements. The back cover is original and in excellent condition. Electronically, the chassis was restored, cleaned and serviced, with all paper/wax and electrolytic capacitors replaced with new ones. The trouble prone selenium (stink cell) rectifier was replaced with a modern diode.
Tubes and resistors were tested and replaced as needed. All controls and contacts were detail cleaned and lubricated. Wiring and other components were replaced as needed.
The radio was aligned, peaked and tuned for optimal reception and quality of sound using the internal loop antenna. It is a very nice looking and sounding radio that will continue to provide many more years of reliable enjoyment if well cared for.
Note: Tube radios consist of a variety of vacuum tubes, capacitors, resistors and other electronic components. This radio has been disassembled, cleaned, and components tested. All non-functioning or suspect components were replaced. Vacuum tubes are similar to light bulbs in that an interior filament heats up inside the vacuum tube. When the filament burns out, the tube will need to be replaced.The tubes in this radio are in good working order. The longevity of the tube and its filaments is related to the length of time the radio is operated and the frequency of turning the radio power on and off.
