Abstract
A phonograph cartridge alignment gauge includes a plate, a cartridge work station and a visual indicator. A method of aligning a cartridge on a tone arm with the gauge, for stylus tangency at two radii, includes fastening the cartridge to the tone arm while the cartridge is on the work station and the turntable spindle is within a combination pivot point-spindle opening of the gauge, to establish stylus tangency at a first radii. The cartridge is refastened to the tone arm while the cartridge remains in the work station but after the tone arm is moved and the gauge pivoted about the combination opening, to establish stylus tangency at a second radii while maintaining tangency at the first. An alternate gauge and method include similar details.
