Rare Small Motorola Pixie Portable Tube Radio Vintage Early 1950s Model 45P1. Untested because I don’t have the batteries to test it. The inside looks very clean, SEE PICTURES.

Motorola Pixie Model 45P1, a notable piece of mid-century electronics history introduced around 1955. Despite its compact size, which resembles early transistor models, it is actually a portable tube radio using specialized subminiature vacuum tubes. Model Variants: The 45P1 designation refers specifically to the Ebony (Black) color variant. Audio: It features a 2-inch permanent magnet speaker protected by a gold-toned metal grille. Portability: Measuring approximately 6″ x 4″ x 2, it was one of the slimmest tube-based portables of its era before transistor technology became dominant. This radio is a “battery-only” set and requires two specific power sources to operate. “A” Battery (Filament): One standard 1.5V “C” cell battery. “B” Battery (Plate): A 45V DC battery. The back cover seems to be missing it’s hinges and a piece of the plastic is missing. That is why the price is lower then others listed.
