This is the original AR turntable. (See AR History for more specific background on its development.) It had a two-piece aluminum platter which was driven by a small synchronous motor. Early versions had two motors to add the extra torque needed to start the heavy platter. A spring-suspended subchassis supported the platter and tonearm. The tonearm had manual adjustments for weight, no real anti-skating, and damped cueing which prevented accidentally dropping needle to the record surface. The tonearm was S-shaped with a single pivot point. The table was extremely quiet and immune to rumble. Early models used solid walnut sides, then they became walnut veneer, and finally walnut looking vinyl veneer.
Note: The AR TA is nearly identical.

*Early design had two motors, the other one was a “start motor” which forced the “run” motor to start up in the right direction. The start motor was belted to the run motor, and the run motor was then belted to the platter.
