(TR -) 55

In the 1950s, the TR-55 was a fresh new product from Sony, and first Japanese transistor radio (10-1).  Here is its description from the Sony archive online…

“At 560 g, the radio incorporates five transistors and is powered by four AA batteries. The use of punched aluminum for the speaker grill also marked a first. The way the grill fits into the case was partly inspired by an etched decorative plate in the dashboards of Lincoln automobiles of the day. Although the dial scale and Sony logo are modeled after previous products, the designers sought a completely new style in other respects, which led to a radio of unprecedented size (89 x 140 x 38.5 mm) and shape.”
