Sub-platter upgrade for Rega.

Machined 6082 alloy Reference sub-platter upgrade for Rega Planar 2, 3, P25, P78 & Rega P2, P3, Rega P3-24, fits nearly all Rega turntables including the new 2016-2018 models. The Reference sub-platter upgrade uses a polished 316L stainless steel shaft which has a PEEK thrustpad installed on the tip of the shaft, this provides a low friction surface for running on top of the ball in the Rega brass bearing sleeve. A longer than standard record spindle allows the fitting of record clamps to your turntable. The sub-platter has a Delrin center boss with a silicon ring to help center the platter. The sub-platter comes with instructions and lubricating oil. You need to add five drops of oil to the Rega brass bearing sleeve before installing the new sub-platter. You should see some oil in between the bottom of the sub-platter and the top of the bearing sleeve which will indicate that the sleeve is fully lubricated.

Sub-platter and bearing upgrade for Rega.

Please note that the sub-platter/bearing upgrade is not suitable for the RP1/P1 due to the fact that they use a small 12mm standard bearing. The sub-platter/bearing upgrade will also not fit newer 2016-2018 Rega designs due to the fact that they use a new bearing that is screwed directly into the plinth, this design can be recognised as it has two holes drilled into the top and no nut underneath. Some RP3/RP6 models use a different housing which is 1mm larger in diameter on the upper portion. In conclusion you need the 18mm brass sleeve with nut design to use this upgrade.

Each sub-platter/bearing kit takes 10 hours to fabricate from raw materials. The sleeve and shaft are made synergistically in each unit for the very best performance. The sub-platter is machined from 6082 alloy billet. The spindle is time cosumingly heat treated and ground. A longer than standard record spindle allows the fitting of record clamps to your turntable. The Reference sub-platter and bearing kit has a Silicon Nitride ball embedded on the end of its shaft running on a Ketron PEEK thrust plate at the base of the bearing sleeve, two Delrin bearing liners at the top and bottom of the 6082 alloy sleeve are separated by an oil gap. This enables the ultimate in quiet running bearings with better lubrication and less friction. A large stainless nut and washer provide more support for the 6082 alloy sleeve, please note that the nut does not need to be overtightened. After installation of the sub-platter/bearing kit it is best to start with about twelve drops of oil and allow the air to escape by carefully pushing down on the sub-platters record spindle with the heel of your hand. The oil will fill the void between the liners and you will know when the bearing is filled to the correct level when you see some oil inbetween the top of the bearing sleeve and the bottom of the sub-platter. You need to add oil until you see this happening.

Sub-platters are also available for the RP6 which allow the use of multi belt pulleys and a sub-platter/bearing is now available for the RP6.
