Zenith Model K725 Post-War AM/FM Radio (1953)

Zenith Model M725 Post-War AM/FM Radio

The Zenith Model K725, introduced in 1953, was a cornerstone of Zenith’s "Super-Symphony" line and represented the gold standard for mid-century tabletop radio performance. Encased in a sturdy, streamlined Bakelite or plastic cabinet, the K725 featured a sophisticated seven-tube AC/DC chassis that utilized Zenith’s famous "Super-Sensitive" FM circuit and a built-in "Wavemagnet" antenna for superior AM reception. It was particularly lauded for its high-fidelity 7-inch Alnico 5 speaker, which delivered a remarkably rich, warm tone that surpassed most competitors in its price bracket of approximately $54.95. The dial featured the iconic circular "Big Dial" design with a smooth, weighted tuning mechanism, making it a favorite for listeners who wanted both ease of use and professional-grade sensitivity. Although it remained a staple of American kitchens and nightstands for years, the K725 was eventually phased out in the mid-1950s as Zenith transitioned to the more compact "C" and "H" series models and began experimenting with early clock-radio integrations.
