Oh, How Far We've Come
By James Grahame
Gerard recently sent a few photos of this old Sony table radio, asking for more information.
It's a Sony TR-72, released only a few months after the company's legendary TR-55 transistor set. This model was imported into Canada between 1956 and 1960 by Manitoba-based Gendis (General Distributors) -- hence the "Gendis / Sony" branding on the tuning knob. These radios were quite popular in Canada for a year or so before the Sony TR-63 made its way to the USA, and a total of around 40,000 TR-72s were produced.
The 10 cm speaker puts out 0.2W of sound, and the set is powered by 3 x 1.5V batteries. There was apparently considerable variation in the color of the wooden case, which adds to the unit's charm and collectability.
Above all, the TR-72 is a wonderful reminder of how much technology has changed in only a few decades.
