SG-1 Tonearm
$2,995.00USD – $4,995.00USD
Benefitting enormously from the work done in developing the Reference Tonearm, the Vertere SG-1 MkII Tonearm provides unsurpassed performance in its class.
features
Counterweight sleeve & tungsten carbide weight insert
The reference tonearm comes with a second tungsten carbide loaded counterweight to accommodate much heavier cartridges than standard. This heavier counterweight also has extra screw‐on end caps to further increase the weight if required.
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.
Aluminum Bearing yoke and 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.
Bearing Transit Screw & Counter Weight Locator
SG-1 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.
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 optimize 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.
SG-1 Tonearm Pillar Holder and Clamp
Precision machined from Acetal the SG-1 Tonearm Pillar Holder and Clamp utilises a Tri-point fixing method and provides the tonearm/cartridge with the required interface to the record player.
Internal Wiring & Contact Connectors
Both the cartridge tags and the 5-pin connector pins are designed, machined and gold plated to our exact specifications for the SG-1 tonearm. The 5-pin connector main body is also machined form solid PTFE for its superior di-electric characteristics. There are two options available for the internal wiring of the SG-1 tonearm:
Standard Pulse wiring
