Little Pioneer.
Little Pioneer that looks like a Sansui. Of course, not at all - but black Pioneers are rare and quite untypical of that brand.
The SX-770 is filled with all that would become bare minimum on a quality component in the years to come and, in addition, "with its oiled wlanut cabinet and black front panel, the SX-770 makes a handsome addition to the decor of any room".
