Designed and manufactured in the UK the feet use the same design principles as our new PWC record stabilizer. The MCRU Technics isolation feet design has its roots in a problem that arose 25 years ago in the age of making sensitive mechanical hard drives to save datastreams correctly under the vibration spectrum of a hovering military helicopter. Tests were carried out to damp rotor frequency vibration using polymers supporting a plate to which the drives were fitted, and adjusting the mass of the plate until vibration at the rotor frequency (rotor rpm and number of blades) was successfully nulled. The combination of mass and polymer Shore hardness and density created a mechanical filter which absorbed the vibration effectively and was broader in spectrum than expected, due to the mass of the plate. 25 years later, now retired from designing defence systems, the designer wondered if the same principle could be applied to damping vibration in a record playing system, and our new isolation feet are one product of these thoughts. Working in a similar way, the mass is suspended on three compressible polymer towers, which sit on point-contact stainless steel balls to provide a rigid path for low frequency noise within the system. The feet are supplied in sets of 4 and are a direct replacement fit for the stock Technics feet.
