Sub Plinth Bearing Damper

About the Sub Plinth Bearing Damper

The Lenco Sub Plinth Bearing Damper is a precision-engineered component intended to improve the overall stability and performance of Lenco turntables. It consists of a 3mm thick stainless steel plate that mounts across the motor well on the underside of the plinth. This plate serves as a bottom bracket to steady the long bearing, attaching via a modified 30mm diameter 'C' clamp and M10 stainless bolts. The design allows the bearing to be rock steady, coupling the thrust pad to the mass of the plinth, which helps reduce unwanted vibrations and improves the turntable's sound quality. The bearing end cap protrudes through a 32mm diameter hole in the plate, allowing for disassembly and re-greasing without removing the damper from the deck. Additional features include a speed control rod and slide mechanism integrated into the assembly, with careful routing for cables and controls to maintain a clean setup. This damper is part of a broader approach to plinth design that emphasizes mass and constrained layer damping to minimize resonance and rumble in idler-driven turntables like the Lenco.
