Vertere SG-1 Super Groove turntable, close to perfection
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 ther highest standards. Both RG‐1 & SG‐1 main bearings are lubricated with Vertere proprietary formulated L‐1G record player main bearing oil. 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. 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. 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 SG-1 MkIII Motor Drive has new enhanced circuitry for speed accuracy, power delivery. The MkII utilises two fully protected output power devices with much improved control of the motor. The new output circuit provides the platter with constant and smoother drive.
Elegant and simple to use with a ‘super charged’ engine under its bonnet. There is an optional dust cover that fully encloses the RG-1 while aesthetically complimenting the elegant lines and design of the record player. 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. ■
