Description
A smartly designed, solid state stereo ‘Custom’ deck with auto reverse and featuring three heads: erase, combined record/playback and an Akai patented cross-field head bias.
Auto reverse was enabled via foil tape inserts for continuous playback in both directions .
Three motors were employed. a hysteresis synchronous three-speed motor for capstan and two 6-pole outer-rotor motors for supply and take-up reels.
Slide type level controls were provided and the standard Akai two-lever transport operation was retained. Tape lifters ensured quiet wind/rewind and ensured minimum tape and head wear. Other features included a solid state pre-amplifier with two integrated circuits (a BIG deal back in the early 1970’s!) , mono/stereo track selector, 100 kHz bias for FM multiplex recording, auto stop/shut-off and instant stop/start button, automatic tape speed equalisation, automatic pinch wheel release, DIN connector with switch for HI/LOW input, headphone jack, 4-digit index counter and oil-finished wooden cabinet.
