Michell Engineering Gyro Dec
The classic Michell Engineering turntable, continuously refined during many years of development to the current level of performance. The Michell GyroDec is a three-point spring-suspended turntable of medium mass, which is compatible with most quality tone arms in existence. Earlier GyroDecs can always be brought up to present spec, and every modern GyroDec can be upgraded to almost the status of the mighty Orbe.

The most obvious task of a turntable is to keep the record at a constant and precise angular speed, without low-rate drift, without audible wow, and without high-frequency noise components which detract from the music’s delicacy.
The 3.5 kg heavy platter, precision balanced, acts as a large flywheel. The Orbe’s platter is made of three GyroDec platters bonded together to form one massive slab of acrylic. The GyroDec and Gyro SE employ a single-thickness acrylic platter, loaded with the gold-plated brass weights which over time have become Michell’s signature. Once up to speed, and aided by the low-friction bearing, the platter only wants to maintain its motion, and not much extra input from the motor is needed.
This motor is a very precise, reliable, and low-noise DC motor that has been selected only after extensive listening sessions and reliability tests. The Orbe models use a version of the same motor with a tacho speed control loop back to the supply. With all turntables the motor is a stand-alone unit, housed in a heavy base of metal (almost 3kg for the Orbe), to elimate vibrational breakthrough to the turntable. The HR and Orbe Controller NC supplies effectively isolate the motor from the potentially poluted mains network.
Drive is relayed to the platter via a precision-ground soft round-section neoprene belt, which runs around the platter’s circumference. This results in a very high reduction of noise transfer from the motor.
The platter should be supported so that it can revolve smoothly, without any extraneous vibrations and motion. This is the job for the main bearing, the very heart of a turntable.We employ a unique inverted bearing that locates the point of rotation above the center of gravity of the platter, and exactly at the height where the drive belt invokes. This makes the platter/bearing a self-stabilising component that can not be provoked into rocking modes.The precision bearing has a case-hardened steel shaft that is secured upright in an oil well, threaded into the subchassis from below. A massive bronze housing, precision-machined as a pair with the shaft, is attached to the platter via the integral record spindle. A thrust ball sits on the flat top of the shaft centralized by an inverted cone in the top of the housing. This housing has a spiral machined into its inner bore to draw a high quality synthetic oil from the bath to the top of the bearing shaft as the housing rotates with the platter. A hole is drilled from the top of the shaft down to the oil well to allow the trapped oil to return to the bottom. This unique oil pumping mechanism results in low friction and wear, and in low rumble and noise. Year after year of operation.
