Rega Planar 2 turntable Lab Report
Rega's new RB220 tonearm may have its new 'zero play' bearings but its design is clearly evolved from both the RB303 [HFN Oct '11] and RB101 [HFN Dec '15] with its 237mm effective length, 23o offset and 11g effective mass. Its performance is closest to the RB303 which shares the same one-piece alloy tonearm (the RB101 has a plastic headshell). This rigid tube offers a well-defined main resonance at 140Hz followed by harmonic and torsional modes at 170Hz and 330Hz at lower amplitude [see Graph 2]. The higher-Q resonances at 500Hz and 900Hz decay quickly and, as we saw them in the RB101 and RB303, are probably linked to the cueing/arm lift mechanism or fingerlift. Play is minimal in both vertical horizontal planes and, while 'zero' is difficult to verify, any bearing friction/stiction is certainly less than 10mg. PM
