Vertere SG-PTA HB Tonearm

At first sight the Vertere SG-PTA HB 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 new 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.

Both the cartridge tags and the 5-pin connector pins are designed, machined and gold plated to exact specifications for the Vertere SG-PTA tonearm HB. The 5-pin connector main body is also machined form solid PTFE for its superior di-electric characteristics. The Vertere SG-PTA HB tonearm is wired with hand-built Pulse HB.
