The Vertere SG-PTA Super Groove Tonearm offers exceptional performance with its unique bearing design and use of quality materials. Its features include a precision Tri-Pivot Articulated bearing, roll-wrapped carbon-fibre arm tube, and bias-curve adjustable anti-skate mechanism.
Vertere SG-PTA Super Groove Tonearm
Benefitting enormously from the work done in developing the Reference Tonearm, the Vertere Super Groove PTA offers incomparable performance in almost any class.
To achieve breath-taking musical performance, the Vertere Super Groove Precision Tonearm utilises a combination of quality materials including roll-wrapped carbon-fibre, stainless steel, brass, aluminium alloys and silicon nitride. Its unique bearing design and versatile anti-skate adjustment make it an ideal partner for highest quality cartridges and turntables.

SG-TPA Tonearm Bearing
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.
SG-PTA Tonearm Tube & Head-shell
Roll wrapped carbon fibre is used in the construction of the arm tube. This provides higher strength and more homogenous fibre structure than a Pultruded or moulded equivalent.
Aluminium Bearing Yoke and Brass Pillar
The bearing pivot is structurally bonded to the precision machined aluminium alloy yoke. The assembly provides the support required for the arm tube, the main counterweight and the anti-skate mechanism.
Bearing Transit Screw & Counter Weight Locator
SG-PTA tonearm transit screw will prevent any accidental damage to the precision Tri-pivot bearing during shipping. And the counterweight locator will ensure accurate repositioning of the counterweight and eliminate the need to setup the Tracking Weight & Azimuth again.
