The Akai 4000DS is a four-track, two-channel stereo reel to reel tape recorder for use with 7" reels. The employment of a highly efficient induction motor and boldly designed flywheel in the 4000DS results in stable tape travel and reduced wow and flutter. This feature coupled with a three head system including Akai's one-micron gap playback head assures clear playback sound. The equipment has been tested and everything works: records, plays, forwards and rewinds. VU meters and their lights work, as well as the counter. But a calibration and general cleaning wouldn't hurt. Tape is not included. One corner of the cover is glued. Look carefully at the photographs, they are part of the description.
