The RB330 is the Planar 3 tonearm, designed using 3D CAD/CAM based on over 35 years of Rega experience. Compared to its predecessors, it has a new anti-skate assembly, a more rigid vertical bearing housing , an integrated arm clamp and a spring with a more readable scale.
The horizontal and vertical bearings are precision, hand-selected, with even lower friction and zero play . Why does it matter? Toward the center of an LP, a 10kHz signal is just 26 microns long and less than 10 microns high: if the tonearm has any play in the bearings, that detail is lost. The low-mass aluminum tube redistributes weight to reduce resonance points.
The phono cable is a Rega-built, low capacitance cable with Neutrik plugs; the mild steel counterweight is 100g. The mounting measurements are standard Rega: low effective mass (11g), effective length 236,5mm and mounting spacing 222mm, with three-point fixing . It is supplied with a mounting template.
