Step back into the dawn of radio with this Westinghouse Aeriola Senior Amplifier, Type AC, Style 326032 – a rare and historic piece from the early 1920s, when wireless listening was still a brand-new frontier. This handsome wooden-cased unit was designed as a two-stage audio amplifier, boosting signals from the Aeriola Senior and other crystal sets so listeners could drive a loudspeaker or multiple headphones. It represents one of the very first commercial steps from headphones-only crystal radios into amplified home listening. Authenticity: Still retains its original instruction sheet inside the lid, complete with Westinghouse branding, wiring diagrams, and connection notes – a true time capsule. Controls: Dual filament rheostats on the front panel, original jacks and hardware, clearly labeled “Detector” and 1st / 2nd Stage. Construction: All-original interior with early transformers, hand-soldered connections, and period wiring – a look at radio technology just as the vacuum tube was changing the world. Condition: Excellent presentation with only light wear consistent with age. Wood case shows a warm patina. Inside components are intact (see photos). This piece is untested and offered as-is for display, restoration, or collection. Collectors know how scarce these early Westinghouse amplifiers are, especially complete and with the factory instruction card still present. Whether you are a serious antique radio enthusiast, a museum curator, or a lover of early 20th-century technology, this amplifier captures the excitement of the “Radio Boom” era like few other items.
