Sony STR-6060
(november 1967 - 1971)

Sony didn't produce many receivers but the 6060 was their first, appearing almost two years after the launch of the original ES units in 1965. Fully solid-state, with a very very serious build quality and the use of a flap to hide secondary controls - a trend many took over much later on!
One can only dream at what would've happened if Sony kept this level of quality for its later (and mostly export-only) receivers!

There are two versions: 6060F and 6060FW, the latter being the most common ; I do not know the differences between the two - besides the switches (black/big/plastic vs. round/slim/aluminium), they seem quite identical... Excellent FM section at any rate.

The 6060FW was briefly available in black circa 1970, but seemingly on order and in Japan only anyway, under the STR-6000 moniker.
