    • 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.

    • A high fidelity turntable system with low aggregate resonance is disclosed. The turntable system comprises a tone arm assembly and a belt-driven platter assembly joined rigidly by a silent substructure of pure aluminum tubing. This low acoustic mass substructure is internally damped beyond its resonance point and is resiliently suspended from a base plate in a mounting cabinet to isolate the turntable system from substantially all resonant feedback. The acoustic mass of the turntable system and, consequently, the resonance, is further reduced by decoupling the tone arm counterweight from the tone arm assembly by means of additional resilient elements.
    • 公开了具有低聚集体共振的高保真转盘系统。 转盘系统包括一个音调臂组件和一个由纯铝管的静音子结构刚性连接的带驱动的拼盘组件。 这种低声质量子结构内部阻尼超过其共振点,并从安装柜中的基板弹性悬挂,以将转盘系统与基本上所有的谐振反馈隔离。 通过借助于附加的弹性元件将音调臂配重与音调臂组件分离,可以进一步减少转盘系统的声音质量,从而进一步减小谐振。
