Vertere SG-1 Tonearm
Two models available:-
With HB Internal Wiring / Without Tonearm Cable
With Standard Internal Wiring / Without Tonearm Cable
Benefitting enormously from the work done in developing the Reference Tonearm, the Vertere SG-1 Tonearm provides unsurpassed performance in its class.
To achieve breath-taking musical performance, the Vertere SG-1 Tonearm utilises a combination of quality materials including roll-wrapped carbon-fibre, stainless steel, aluminium alloys and silicon nitride. Its unique bearing design and versatile anti-skate adjustment make it an ideal partner for any high-quality turntable.
FEATURES:-
SG-1 TPA Tonearm Bearing:
The unique Tri Point Articulated (TPA) bearing is comprised of three precision silicon nitride balls and stainless pivot. The pivot point centred between the 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.
SG-1 Tonearm Tube & Headshell:
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.
The head-shell is machined from aluminium alloy and connected to the arm tube via structurally bonded alloy end insert. Naturally non-resonant and higher strength to weight ratio of this configuration provides the optimum cartridge platform.
Aluminium Bearing Yoke & Stainless Pillar:
The bearing pivot is structurally bonded to the aluminium alloy yoke. The yoke assembly provides the support required for the arm tube, the main counterweight and the anti-skate mechanism.
The pivot point and the counterweight centre of gravity are vertically positioned to be as low as possible. This in turn retains the tonearm in its most stable position.
Arm/Cartridge Resonance Frequency & Fine Tracking Weight Adjustment:
An adjustable and de-coupled stainless ring allowed to move along the arm tube provides fine tracking weight adjustment.
The relative position of this ring and of the main counterweight can also be used to alter the arm/cartridge resonance frequency and optimise play back performance.
SG-1 Tonearm Main Counterweight:
Attention to detail is clearly seen in the polished stainless steel counterweight and peg.
Two pairs of silicone de-coupling rings are neatly sandwiched between three machined Acetal retainers to provide the necessary grip for location and the required isolation of the counterweight.

Tonearm Lift/Lower Mechanism Plate Assembly:
Bespoke components are used for every part of the SG-1 Tonearm. These include its machined Acetal arm clip and polished stainless steel cueing device.
