In my Global/Zephyr book I talk about a particular Japanese radio manufacturer who made some of the greatest of the early Zephyrs. That same manufacturer made this absolutely stunning Packard Bell. It even has the same knob and earphone configuration as the Zephyr AR-600. Can you guess the manufacturer? This great Packard Bell has no model number that I could ever find other than a TSR-5901 number on the circuit board. As with the Zephyr, the unusual dial configuration necessitates a vertical placement of the ferrite antenna inside. But the star of this radio is the styling, and especially the curvy inset plastic grille. Note that even the back of this radio is stylish--look at those louvres off to the right side. The radio is 4 1/4" tall. And the manufacturer? Aiwa.
