First 3-tube radio



First 3-tube radioThe first 3-tube radio (R-31), was designed after long hard work. Though radiobroad- casting had been expanding into Japanese households at a rapid pace, the radio sets in those days were very often unreliable. So the R-31 was manufactured with the aim of making a radio that "wouldn't break down".
An inventor at that time owned a patent for a critical radio part and this presented a major problem for the design. Konosuke Matsushita bought this patent in October 1932 and made it available free to manufacturers in the industry. This contributed greatly to the expansion of the entire industry and was highly praised by people in various fields.
