Up for sale is a meticulously restored piece of American radio history: a 1933 Zenith Model 715 tombstone radio.

This particular unit has been professionally serviced and thoughtfully upgraded to bridge the gap between classic analog warmth and modern convenience. Design & Cabinet Aesthetics. The Model 715 features one of the most celebrated and intricate cabinet designs of the era. The upright tombstone cabinet boasts a gorgeous, matched butt-walnut front overlay framed by elegant architectural pilasters and an exceptionally ornate wooden lattice grille over the speaker cloth. On the front, the beautiful brass escutcheon frames an orange-lit vertical drum dial. Right above the dial sits Zenith’s iconic early mechanical Shadowgraph Tuning Indicator, which projects a narrowing shadow onto a small screen to let you visually tune into a station’s peak resonance. The Chassis & Technical Restoration. Under the hood, this radio features a powerful 8-tube superheterodyne circuit that delivers incredible selectivity and room-filling volume through its heavy-duty 8-inch dynamic speaker. Original Tube Lineup: 58 (RF Amp), 58 (Mixer), 56 (Oscillator), 58 (IF Amp), 55 (2nd Detector/AVC), a pair of 59s running in a push-pull power output configuration, and an 80 rectifier. The Restoration: The chassis has been thoroughly cleaned, tested, and restored. The power section and entire circuit have been checked for stable, safe operation, ensuring those classic filaments glow perfectly and perform reliably. Modern Upgrades: Bluetooth & Aux Input. To make this masterpiece functional for today’s music lovers, a seamless modern upgrade has been installed. Auxiliary Input & Bluetooth Module: An auxiliary input jack has been cleanly integrated into the circuit, complete with an external Bluetooth receiver. The Best of Both Worlds: This allows you to stream your favorite podcasts, Spotify playlists, or internet radio directly from your smartphone, tablet, or computer. The audio routes directly through the radio’s legendary push-pull tube amplifier stage, giving your digital music that unmistakable, rich, velvety vintage tone. This unit will be double-boxed, padded extensively with premium packing materials, and fully insured to ensure it arrives at your doorstep in the exact condition it left the bench. Tubes may be wrapped individually inside the cabinet if necessary for safe transit. Don’t miss the chance to own a fully functional, upgraded masterpiece from the golden age of radio engineering!
