AR Turntable Models

 

AR XA with Felt Mat

XA

1962-1979???

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 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.

XB

1972-197?

The XB was introducted around 1972 for $130 (at this time the XA was $115) with a plywood veneer base, the tonearm lift, no mechanical damping, black plastic headshell, and a stainless steel counterweight. The metal top plate was always black and the power switch was a rocker type on the right side. The brushed steel or aluminum AR logo surrounded the power switch and cueing lever. The tonearm rest was metal.
