In Japan the TR-63 sold for 13,800 yen, and the original export price was U$39.95. That's an indication of the progress made in the electronics industry in the past 50 years. By comparison, the Cell processor chip in the PS3 contains two to three hundred million transistors. The TR-63 contains a whopping 6 transistors. A foreshadowing of the Walkman and iPod, perhaps? But unlike desktop radios of the day which were promoted under the idea of "a radio in every home", the TR-63 was uniquely marketed as something each person could own and carry with them. So story has it that company salesmen wore custom-made shirts with slightly bigger pockets to show off the TR-63's small size. It seems "pocket-sized" was a bit of a marketing gimmick at the time - although smaller than any competing product, the TR-63 was a bit too big to fit into a standard shirt pocket. ![]() All general purpose transistors should work in this circuit. It became a huge commercial success, over 100,000 units were sold. Canadian Antique Radio Schematic Diagrams - JustRadios - Specializes in Antique Radio. The TR-63 was introduced in 1957 - it was the first "pocket-sized" transistor radio ever made and the first Sony-branded product exported to North America, by the then-named Tokyo Tsushin Kogyo company (Tokyo Telecommuncations Engineering Corporation). TESTED Vintage Kenwood KR-6600 AM-FM Stereo Receiver WOOD CASE - MINOR. If we're going to tear down Sony consumer gadgets, why not start with one of the earliest? The TR-72 was in production for about 5 years (estimates vary), and it went through several different iterations, with several different schematic diagrams. Here's a Sony TR-63 transistor radio - I forgot I had one until reminded of it by the ifixit Sony teardown promotion. This teardown comes with a bit of a history lesson :) ![]()
