Vertere SG-PTA Tonearm

At first sight the Vertere SG-PTA Tonearm may come across as a uni-pivot, it is in fact anything but a uni-pivot. A uni-pivot will ‘skate’ about on its bearing point of contact while the tonearm moves side-to-side and up-and-down. This is because there is no such thing as a point; there is in fact one surface supported by another and sliding relative to each other.

And because of this there is always some ‘skating’ of the contact point on the support bearing surface. Although the ‘skating’ or ‘chatter’ may be in fractions of microns but so is the magnitude of some of the information stored in the vinyl groove.

To eliminate this ‘loss’ of information due to unwanted bearing chatter, Vertere have designed a Tri Point Articulated bearing or TPA. Three silicon nitride precision balls and a precision machined pivot point provide the support and the articulation for the arm. Although the tonearm may appear to behave as a uni-pivot, it is however, without any of the bearing ‘chatter’, preserving as much of the signal information as possible. The result is a life like dynamic response with unexpected clarity, musicality and detail – truly unparalleled.

The unique Tri-Pivot Articulated (TPA) bearing is comprised of three precision silicon nitride balls captive in a precision machined Acetal ball retaining ring supporting the super precision machined stainless pivot. The pivot point centred between the silicon nitride balls provides flawless support and articulation.

TPA eliminates bearing point ‘skating’ and allows the stylus to track the most delicate pieces of information that are typically lost with uni-pivot designs. This ensures accurate play back due to the strict adherence of the stylus to the record groove.
