Vintage Tube Amp

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.

Offered for sale are the 3 tubes as titled and pictured. These particular 3 tubes tests strong and are closely balanced / matched. The tubes’ test results are displayed in the photos (New 5751 Spec 100% = 1,200 Gm). Note: Even though this tube is often considered interchangeable with the 12AX7, the 5751 does have a bit less gain than a 12AX7, so the test results displayed are the actual Amplitrex specs for the 5751. Also, these tubes are labeled Westinghouse and there are no other EIA codes or numbers on them. So far, these boxes are still just a concept and in the prototype stage (3D Printed). Any and constructive feedback on the idea is welcomed and appreciated. Eventually I plan to offer these boxes for sale by. Themselves, but not quite yet. See the photos for physical / cosmetic condition. Notes Regarding Tube Tests. All tubes are tested on an Amplitrex AT-1000 tester in the automatic Fixed Bias Mode (for the most conservative results). Test Results are for a general reference only, and are not a guarantee of performance, nor a guarantee of how they will test on your tester. No real world (audio) performance measurements are taken.

Also, these tubes are labeled Westinghouse, and there are no other EIA codes or numbers on them, but based on their construction style. And by comparison of hundreds (if not thousands) of other tubes over the years, they appear to be of Raytheon make / origin.
