A beautifully machined stainless steel endstub will now be shipped with every counterweight purchase. This will ensure a precise fit of the endstub with the counterweight assembly.
Groovetracer will not be selling endstubs separately at this time. They will only be included with the purchase of a counterweight.
There are now three different subplatter models available from Groovetracer™. All three models are currently in stock and ready to ship.

The Groovetracer acrylic platter has been slightly redesigned to carry even more mass than the original design. It is now being machined to 26mm thick. The main reason for going thicker came from the realization that the supplier of the raw material could no longer deliver the stock required to make the 24mm thick platter, and rather than go to a thinner design and make a platter with less mass, the decision was made to go to the next larger stock thickness to slightly increase mass. This slight increase in mass results in a platter weighing 4.5 pounds that precisely matches the weight of the Rega glass platter.
The previous 24mm thick platter was very close to the exact same weight as the 12mm thick Rega glass platter so the new design will result in no loss in mass at all. For example, the mass or specific gravity of acrylic is only 1.2, whereas glass is 2.4 which simply means that any acrylic platter under 24mm thick will result in a loss of rotational mass.

Groovetracer™ has taken their original subplatter design to an even higher level of performance by mounting a sapphire to the load bearing surface of the bearing axle to provide an ultra low friction interface with the Zirconia ball bearing.
In simple terms this translates to a lower noise floor which in turn results in a blacker background for the musical information to evolve. Sapphire is second only to diamond in hardness so the life of the bearing assembly also increases. This means you can enjoy trouble free performance from your turntable for many years to come .
