Main bearing assembly

Directly derived from the unparalleled RG‐1 main Bearing, the SG-1 performs second only to the RG‐1. Based on the same design, geometry and similar precision engineering techniques, the SG‐1 bearing is made to our highest standards. Both RG‐1 & SG‐1 main bearings are lubricated with Vertere proprietary formulated L‐1G record player main bearing oil.

Turntable motor

One look at the record player motor assembly and the depth and innovativeness of its design become apparent. Using precision bearings to articulate the proprietary aluminium alloy motor housing keeps the motor continuously synchronous achieving constant belt tension. Simply put, it drives the platter at constant speed without interference.

Main platter

RG-1 platter assembly is a unique two piece super precision machined aluminium alloy design that provides friction-only damping of the platter assembly.

The main platter has a critically designed surface profile on its top side that perfectly matches the underside of the reference platter insert. The two parts fit so precisely that the assembly creates a linearly damped, non‐resonant structure.

Tempo Motor Drive

It is absolutely critical that the record player motor is powered and controlled faultlessly to ensure a full and musical performance of the record player. The new Tempo takes control of the record player motor and provides it with smoother drive with lower noise and lower distortion. Its internal circuit as with the reference motor drive is uniquely microprocessor based providing a pure sine wave in the digital domain and then converted to analogue via an on-board DAC. Two waveforms are derived, a cosine and a sine, which are then amplified using two bridged amplifiers to power the motor.

SG-1 turntable dust cover

There is an optional dust cover that fully encloses the RG-1 while aesthetically complimenting the elegant lines and design of the turntable.

The main section covering the top, front and the back is a one piece 6mm clear cast acrylic providing support and rigidity with cut-outs for motor drive and tonearm cables. The sides are made from 3mm clear cast acrylic also including hand-grip cut-outs for easy placement and removal of the cover.

A Vertere emblem, laser engraved on the top adds the finishing touch to this elegant and practical record player dust cover.

Special Metallic Finishes

Vertere Special Metallic Black, Pearlescent White & Champagne finishes are now available for the SG-1 record player at a premium.

Following in the footsteps of the RG-1, these lustrous, vibrant colours provide perfect alternatives to the original Clear finish of the SG-1.

Clear cast acrylic was carefully selected for SG-1’s plinth material as it provides the most stable and acoustically suitable platform for all its critical components. The specially formulated paint and method of printing of these glistening finishes enhance the aesthetics without any compromise in performance of the SG-1 record player.

The Vertere emblem printed on the top plinth adds the final finishing touch.
