All Michell turntables currently employ a unique inverted bearing that locates the point of rotation above the center of gravity of the platter, and exactly at the height were the platter takes up the drive belt. 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, which is 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 stainless steel 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. An off-center hole is drilled from the top of the shaft down to the oil well to allow the trapped oil to return to the oil well. This unique oil-pumping mechanism results in low friction and wear, and in low rumble and noise. It was designed to last a lifetime.

Converts acrylic platter GyroDecs or Gyro SE to the Orbe Platter and screw-down clamp. Brings your GyroDec that much closer to the sound quality of the Orbe. We recommend the DensoDamp chassis danping compound too. Also, if you do not have the latest 2-piece decoupled suspension towers, you should consider this as well.

(MKI GyroDecs require a change to later style springs. — Call for details.)

Prewired stand-alone motor housing will accept your old AC Gyro motor and top plate, or the new DC Motor Upgrade Kit. When fitted to early GyroDecs with AC motor, this housing virtually eliminates all motor noise. Comes pre-wired with a power lead terminated in a mini XLR connector. Machining of a clearance hole in the GyroDec's baseboard is required, unless you are converting your GyroDec to the SE configuration, with no base or dust cover. (See Gyro SE Spyder kit below). Some soldering is required.

If you own an older AC-powered GyroDec or Gyro SE, you should consider this upgrade which produces a quantum improvement in sound quality, while totally eliminating mechanical resonance produced by the older AC motors. This kit outperforms the old AC motor, even those running off the upgraded QC power supply, yet costs much less! The new DC motor comes pre-assembled to a new top plate with switch, that simply drops into your present Gyro motor housing. The DC power supply has an internal speed adjustment, and is the same as the one used on the current GyroDec, Gyro SE and TecnoDec. Some soldering is required.

When used with the Stand-alone Motor Housing Kit, will convert a GyroDec to a Gyro SE. If you are willing to give up the dust cover and base on your GyroDec for better sound reproduction, or your cover is broken, then this is the kit for you.

John Michell, one of audio’s best known and most respected audio engineers, has come up with a versatile, precision-engineered, geometrically correct counterweight system, suitable for all Rega arms and their various derivatives. Will fit the Rega RB250/300/600/700/900/1000 arms and their variants such as Moth, Audio Note, Goldring, and Origin Live OL-1 arms. The TecnoWeight will handle a wide range of cartridges, with weights from 3g to over 13g. This versatility is achieved by supplying two counterweights for cartridges in the 3-6g and 6-13g ranges. The chosen counterweight sits on a new stub shaft that allows precise adjustment of tracking weight in increments of one tenth of a gram. The Counterweight itself is underslung below the main axis of the arm tube to bring the centre of gravity of the whole arm assembly in line with the stylus tip. The TecnoWeight’s precision engineering and fine adjustment capability has a particularly large impact on the performance of the RB250 tonearm. The replacement of the plastic stub shaft and large diameter counterweight, allow for much more control, precision and detail in its musical reproduction. When used with RB300/600 arms, the TecnoWeight dispenses with the need to use the arms own somewhat questionable tracking force system, which further improves sound reproduction. The TecnoWeight is standard on Michell's own TecnoArm.

In the May 2006 issue of STEREOPHILE Michael Fremer gave the Tecnoweight a wonderful review.

Conclusion: "It's easily the most ingenious and impressive Rega retrofit I have seen"

Finally, a clever, inexpensive, solution to a perplexing problem! No more arm removals to insert shims. Simply install the Michell VTA Adjustment Base on your Rega RB250, RB300 or RB600 tone arm, or any variants (Origin Live, Moth, etc, and you can adjust the vertical tracking angle in minute increments without losing the rigid mounting so important to proper sound reproduction. Requires a 1 1/8" diameter mounting hole. The VTA adjuster, at its' minimum setting, raises the tone arm by 1.75mm, which is slightly less than the thinnest shim (2mm) that REGA manufactures. The VTA adjuster is standard on Michell's own TecnoArm. Combined with Michell's Rega Finger Nut, adjustments are fast and painless. Will only fit Rega variants with threaded base (not RB700/900/1000).

To adjust VTA, just loosen the tone arm hold-down nut, rotate the VTA Adjuster Base to raise or lower the tone arm, then retighten the hold down nut. So simple! We recommend the use of our RegaWrench or Rega Finger Nut for even easier adjustments.
