Technics SL-1000R turntable/arm Lab Report
In common with Technics' first S-shaped tonearm, this latest iteration is remarkably free of debilitating resonances despite its detachable headshell and ostensibly complex arm lift and rest, spring-tension bias adjust, double-axis gimbal bearing and adjustable height control. In practice the cold-drawn magnesium tube looks to have a diffuse bending mode around 95Hz with higher-Q harmonics deferred to 200Hz and 300Hz, all of which are at significantly lower amplitude than competing designs. The scatter of resonances between 1-2kHz might come from the headshell collar and lift lever but they are very short-term [see Graph 2]. The custom gimbal bearing proved both free of play and measureable friction (<5mg, both planes) while the downforce calibration was accurate to within <±5%. In every respect, this is the ultimate plug-and-play vinyl solution! PM
