The Rega RB330 tonearm embodies over 35 years of experience in tonearm design by the British audio manufacturer Rega. This model, included as standard on the Rega Planar 3 and Planar 6 turntables, incorporates several improvements and innovations that enhance its performance and reputation among vinyl enthusiasts.
The RB330 features a one-piece tonearm tube and headshell made from die-cast alloy, ensuring high rigidity and low resonance. The tonearm tube has been redesigned using an intelligent redistribution of mass, which has reduced potential resonance points. This design choice contributes to the tonearm’s ability to extract more information from the record grooves.
Rega has equipped the RB330 with high-precision horizontal and vertical bearings, offering extreme stability and almost frictionless movement. The tonearm achieves near-frictionless movement in both planes while maintaining virtually no measurable play in the bearing assemblies. This unique feature is a hallmark of Rega’s tonearm designs and ensures precise tracking of the record grooves.
The RB330 also features a new bias assembly, which has been redesigned to improve performance. The bias compensation system is magnetic and frictionless, contributing to the overall precision of the tonearm.
The vertical tracking force (VTF) is applied using a dial located on the side of the vertical pivot housing. The mechanism incorporates a spring that applies maximum negative VTF at the zero setting, effectively disengaging when the VTF exceeds three grams. This design allows for precise adjustment of the tracking force according to the requirements of the chosen cartridge.
The anti-skating force is applied by a simple slider mechanism, which can be easily adjusted to compensate for the inward pull of the tonearm during playback.
The RB330 is equipped with a low-capacitance phono cable manufactured by Rega, terminated with high-quality Neutrik plugs. The wiring is slightly unusual, as the tonearm tube is grounded via the left channel ground wire, eliminating the need for a separate ground wire to connect to the preamplifier. This wiring configuration helps minimize electrical interference and maintain signal integrity.
The Rega RB330 tonearm has been praised by audiophiles and professional reviewers for its exceptional performance and sound quality. The precision and stability of the tonearm allow it to accurately track the record grooves, extracting a wealth of detail and information from the vinyl.
The low-friction bearings and optimized mass distribution of the RB330 contribute to its ability to reproduce music with clarity, dynamics, and a sense of rhythm and timing often associated with Rega turntables. The tonearm’s low effective mass of 11 grams makes it compatible with a wide range of cartridges, allowing users to fine-tune the sound to their preferences.

Replaced the original tonearm on my REGA turntable, which was showing signs of weakness after 15 years of heavy use. Very easy to install. Perfect.
