Early 1957 Sony TR-63 with the Tokyo Tsushin Kogyo Ltd stamp on the back (later models had SONY JAPAN stamped on the back). Serial number 27288 with grey Sony branded transistors. No cracks! Untested. Virtually no wear on the coin slot. Very minor scuffs. Please check the photos carefully for condition. I'd give this one an A- for condition. It is priced accordingly.

The TR-63 is believed to be the first consumer product released by Sony onto the American market and it was also Sony’s first pocket size transistor radio. According to the Milwaukee Journal, Sony had shipped about 25000 transistor radios to the USA by January 1958. Ref: The Milwaukee Journal January 23, 1958.

The TR-63 was touted as the world’s smallest transistor radio at the time of its release and measures just 112mm x 71mm x 32mm. Sony marketed this radio as ‘pocketable’ however it was just slightly larger than the standard mans shirt pocket. In order to overcome this problem Sony founder Akio Morita devised a clever ruse; he had special shirts made for his salesmen with pockets just big enough to slip the TR-63 into. Hey now that’s lateral thinking!

The TR-63 was one of the last Sony radios to feature the old Sony logo. By 1958 Sony had stopped using this logo and moved onto the more familiar one we all recognize today.
