SONY mod. TR-620 - Japan 1960 

Sony mod. TR-620 - Japan 1960  - Pocket radio with AM band, circuit is a superetherodyne with 6 germanium transistor: 2SC73, 2SC76, 2SC76, 2SD65, 2SD65, 2SD65, frequency coverage from 535 to 1605 KHz, and IF frequency at 455 KHz. Power supply: one 9 V battery transistor type (S-006P, 6F22). The dimensions are: 6 x 9 x 2.7 cm. The TR-620 was he next generation or the re-design of the classic TR-610. The 620 is smaller than the 610 and it was really a "breast pocket radio".
