Description

Also sold as the Roberts 771X in the USA.

The cabinet came in two versions:  teakwood or vinyl with a carrying handle on it.

Like all single motor Akai’s the speed change was handled in an unorthodox manner:  the motor ran at two speeds (the little switch on top between the reels) and the third (and optional fourth) speed was achieved by fitting a capstan sleeve.  The playback equalisation was changed via a little switch.
The machine has two built-in speakers and the two “flaps” on the side are a kind of sound reflecting device that was often used on Japanese tape recorders of this era.
