Small vintage transistor radios don't get any better than this
"shirt pocket" Sony radio. The Sony
TR-620 was introduced into the UK in June 1960, it's extremely compact using the new generation of
sub-miniature components. At the time this transistor radio set new standards for quality and
style and even today this radio is in a class of its own.
The TR-620 was moulded in four colours,
White, and Coral Red. The radio was sold in a presentation
box that included a black leather case, earphone, external aerial,
polishing cloth and user guide. The radio cost 18 guineas
(£18.90) when launched in 1960 in the UK. Today these
transistor radios are very collectable and sell on e-bay
between £30 and £150 depending on the radio condition and the original
