RCA Victor P-331
The insides of this radio are somewhat unique and of a primitive looking design. While it does use a printed circuit board for the core electronics, the tuning capacitor, volume switch and one of the battery holders are mounted on a hand-built aluminum board. The boards are connected by the two screws you can see to the right of the black plastic battery holder. Speaking of batteries, here again we have a unique design. The radio is powered by four AA-cell batteries. Two of these batteries sit side-by-side in the black holder, and the other two sit atop one another in the battery holder molded into the cabinet itself, (shown at lower left).
The Sony oval transistors in this one are: 2T73 - 2T76 x 2 - 2T66 - 2T65 x 2; [1T23] [1T41]
The transformers are by Yaou Electric.
Oh, and this relatively large coat-pocket radio also sports a relatively large 3-1/2" speaker.
