A systems approach is used to develop criteria for phonograph preamplifier design in order to better align results with real-world considerations. Specially cut test discs have been prepared and analyzed with various playback systems for symmetry, speed, and distortion. Low-frequency stability requirements are analyzed in the light of infrasonic warp content. RFI performance is given special attention.
