The OKI 555 was a light
weight, solid-state, portable stereo quarter-track tape recorder, complete
with two detachable ‘OKIdizine’ two-way speaker enclosures which formed
the lid to the recorder when not in use.
The unit featured a rather unconventional set of transport function controls
– these can be seen in the picture at left – in the form of four levers,
two on each side of the head block assembly.
Features included two speeds (7½ & 3¾ ips), sound-on-sound,
auto shut-off, tape counter, straight-through amplifier facility, two
heads and one motor.
Made in Japan, OKI was distributed in the USA by the Newark, New Jersey
company of Chancellor Electronics Inc.
Price when new, $349.95 (1966 HiFi/Stereo Review tape recorder Annual).
