This is a beautiful, pre-war 1940 Zenith Model 6-S-439 tabletop vacuum tube radio. Built in Chicago in 1939 for Zenith’s iconic 1940 lineup, this unit features the legendary Chassis 5678 Serial No. Tested & Working: The radio powers on smoothly and tunes into stations well. Audio Quality: Produces a very nice, warm, and clear vintage tube sound. Controls: Tuning dial, presets, and adjustment knobs rotate smoothly and operate as intended. Wood Cabinet: In nearly flawless cosmetic condition! The Art Deco horizontal louvers and wrap-around wood finish are stunning, showing incredible luster and minimal wear for an 85+ year-old piece. Grille Cloth & Dial: The original grille cloth is intact, taut, and clean. The dial face and glass are beautifully preserved. Flaws to Note: The rear wood particle backplate has a crack in it. This does not impact the stability of the cabinet, the audio performance, or the front-facing display value of the radio. (Please see pictures for close-up details). 15.75″ W x 9″ H x 9.5 D. Power: Standard AC cord with original bakelite plug.
