Standard sub-platter upgrade for Rega.

Machined 6082 alloy sub-platter upgrade for Rega Planar 2, 3, P25, P78 & Rega P2, P3, Rega P3-24, fits nearly all Rega turntables including the new 2016-2019 models. The standard sub-platter upgrade uses a precision ground and polished bearing grade 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. This low friction non metalic surface will reduce the noise floor of your turntable. A longer than standard record spindle allows the fitting of record clamps to your turntable. The sub-platter has a Delrin center boss. 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.

Reference sub-platter and bearing upgrade for Rega.


Please note that the sub-platter/bearing upgrade is not suitable for the RP1/P1 due to them using a small 12mm standard bearing. The sub-platter/bearing upgrade will also not fit newer 2016-2020 Rega designs due to them using 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. In conclusion you need the 18mm brass sleeve and 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 consumingly ground and polished from bearing grade stainless steel. 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 (can be seen in image 4 to the right). 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 which also has a larger diameter top lip to allow better contact with the plinth, 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.
