The first Voxon transistor radio, and one of the earliest Italian transistor radios, but it wasn't the first. And the same goes for two other early Italian transistor radios, the Radialba Model 2010 by Radio Allocchio Bacchini (though this was in fact the first Italian pocket radio), and CEI's Beta/Selonyx Hermann.
From correspondence I've received from Italian radio collectors, the Allocchio Bacchini
2001 is now considered the prime candidate, but according to Aldo Andreani, "this could be the real first Italian transistor radio, but so far no one knows if it ever entered the market".
This Zephyr 725 was Voxson's first transistor radio model. A two-band MW/LW set, employing RCA transistors and a vernier tuning dial and a lift-up handle — seems to me the only thing left out here was good Italian design!
