Designed and manufactured from a combination of carefully selected materials to reduce, absorb and dissipate external vibrations, this 1877Phono Lycan 270G pressure puck is suitable for platinum bearings up to 6mm deep. It is precision machined from a block of 6061 aircraft grade aluminum for a total weight of 270g. Its center ring is made of pressure-fit Delrin and separated by two silicone seals. The Delrin not only dampens vibrations but also protects the bearing of your turntable from wear and scratches due to continuous use. The bottom of the puck is equipped with a non-marking leather pad to further absorb weight and protect your vinyl's label from scratches and scuffs. The Lycan will fit a wide range of turntables to help minimize vibration and keep your records flat on the platter.
