Philco Transitone Portable Radio, Model 49-602, 1948-1949

This radio marks several shifts in radio design and materials. As manufacturers began using plastic for radio case designs, the color palette widened. Transitone consumers could choose between ivory, maroon, brown, and green. This unit also echoes the rising trend of portability. Tube-driven radios like this would eventually yield to competition from the spread of transistor technology in the mid-1950s.
