1963 Сокол (Sokol)

Coat pocket radio, thermoplastic cabinet
6 x 3 7/16 x 1 1/2 inches / 152 x 87 x 38 mm
2-band LW/MW, seven transistors (Russian, MП15, MП41, 2x П14, П402, П422, one unidentified, + д9B diode)
Superheterodyne circuit
One standard 9-volt battery
Manufactured at Moscow Radio-TV Works, Moscow

The Сокол was one of only a very few Soviet transistor radios that made use of underpainting on its dial area. And at least for the Сокол, the underpainting process hasn't lasted the test of time — I've yet to see even one example that doesn't have some sort of damage — most have large swaths of the underpainting missing.

The Сокол shares the same cabinet layout and nearly the same circuit as the relatively more rare 1963 Топаз-2 (Topaz-2) (see cabinet and chassis comparison photos below), the main difference being their transistor complements. The "unidentified" transistor here is encapsulated in a very well secured round aluminum canister found just below the speaker in the chassis photo below (on the Topaz-2 chassis, this transistor is a П403).
