This is a 6-transistor AM band radio from Mitsubishi Electric. The frequency is displayed in Kc, so I believe it was released before 1968 (Showa 43). The size is approximately 108 x 65 x 35 (mm), and it weighs 245g (including batteries). The power source is 3 volts from two AA batteries. The reception sensitivity is good. The major broadcasting stations that cover the location of this radio can be received with good sensitivity. Both the volume and tuning dials work well. In terms of appearance, the top, bottom, and four sides of the case have lost their luster. This is likely because it was kept in a rather tight carrying case. Please understand that this radio has a well-used feel from many years of use. Please purchase it as a vintage collection of Showa retro items, not for everyday use.
