Acoustic Research XB1


The National Association of Broadcasters specifies that turntables used for broadcast work must meet certain standards in performance and dimensions.

The AR XB1 meets these standards, except for starting time, including the tolerance limits of the center spindle, which are +0, -0.0005", with a nominal diameter of 0.2830".

Some records have center holes smaller than specified by industry standards, and there may be a few which are tight on the spindle of the turntable.

This can usually be fixed by inserting and twisting the point of a pencil in the center hole to remove any scraps of plastic material left after moulding.

With A/C synchronous motor. Introduced in 1972
