全部拍賣 / Music & Musical Instruments / Allocchio Bacchini & C - Allocchio Bacchini Tube stereo receiver
Splendid and exceptional piece of Italian industrial archaeology, dating from the mid-1920s (circa 1924-1926). It is a module/chassis for a vacuum-tube radio receiver with external valves produced by the famous pioneering Milanese company Allocchio Bacchini & C. (Milan, serial number 2858). The item is presented in an extraordinary state of preservation, ideal for discerning collectors of vintage radio technology, retro decor, and scientific curiosities. Main features and technical details: Front panel: Original ebonite with engraved and etched inscriptions in perfect condition. It features period terminals for separate battery power: 4V for the filaments and 80V for the anode. Valve included: Complete with its rare original triode thermionic valve positioned on the top. The internal structure of the valve and its supports are stable; the inner filament visible from the outside appears visually intact (not broken). Interior and wiring: The wooden case encloses an impeccable, never-tampered interior. Original capacitors bearing the interwoven AB logo of Allocchio Bacchini (values 6 mμF and 4 mμF), the central coupling coil, and the typical rigid geometric wiring with cloth-insulated insulation of the era are present. Aesthetic conditions: Excellent vintage condition. Solid wooden structure, absence of destructive rust blooms or mold. Very light patina of time that enhances its authenticity. Notes for the sale: Historic collectible item sold as a decorative display element. Since this is a 1920s radio device, it has not been electrically tested and is sold as-is ("untested / operation not guaranteed").
