"The "The AR Turntable" was favorably reviewed by Peter Mitchell in Audio magazine (1984), but he did complain that the vertical pivots were nearly a half-inch above the record surface, meaning that some warp wow may be audible when playing imperfectly flat records. However, the perfect match for that arm was the Shure V15, and the resonance with the damping brush down gave a 2dB rise in the 11-16Hz range, rolling off below 9Hz. Not bad - the damping factor of this particular combo. A few finishes were offered, mostly oiled walnut in the states and a deeper cherry finish in the UK. The edges of the AR TT are rounded, as is the ES-1, the EB-101 being a bit boxier looking and an inch smaller all around.
An earlier model of the AR TT would sometimes develop bearing noise after a while. The problem was strictly QC, and a new motor was introduced in 1985, with better bearing materials and finish. Most of the tonearms developed severe sticking problems. The cueing devise was redesigned and field replaced under warranty."
