This is a 6-transistor radio from Sanritsu Electric. It was manufactured around 1960 and I believe it's a US specification radio. The size is approximately 127 x 87 x 36 (mm) and it weighs 407g (including batteries). The power source is 4 AA batteries, providing 6V. Reception sensitivity is good, but when tuning, especially in the high-frequency band, there is an oscillation sound "peep" or a "scratchy" sound when turning the variable capacitor. In terms of appearance, there are scratches and dirt on the front panel and case. Please understand and acknowledge that this radio has been used for a long time. Please purchase it as a vintage collection of Showa retro, not for everyday use.
