Weighing approximately \u003cstrong\u003e450 g (15.9 oz)\u003c\/strong\u003e and machined from corrosion-resistant stainless steel, the AT628a sits over the turntable spindle to hold records firmly in place, reducing resonance for measurably improved playback clarity. Two recessed inner rings on the underside accommodate records with slight warps or spindle-hole bulging, ensuring consistent contact across the record surface. Made in Japan and compatible with spindles up to \u003cstrong\u003e21 mm in length\u003c\/strong\u003e, the AT628a pairs naturally with mid-range to premium turntables and adds a purposeful, modern aesthetic to any deck.\u003c\/p\u003e\n\n\u003ch2\u003ePrecision-Machined Stainless Steel Construction\u003c\/h2\u003e\n\u003cp\u003eThe AT628a is machined from solid stainless steel, a material chosen for its rigidity, density, and long-term resistance to corrosion, oxidation, and tarnishing. The precision machining process produces a stabilizer that seats evenly on the record surface without rocking, ensuring the clamping force is distributed uniformly across the label area. The exterior profile is contoured for easy gripping, allowing the stabilizer to be placed and removed without fumbling. Unlike acrylic or aluminium stabilizers available from other manufacturers, the stainless steel construction of the AT628a provides a higher mass loading effect, which increases the coupling between the record and the platter mat and reduces the micro-vibrations that the stylus would otherwise read as noise.\u003c\/p\u003e\n\n\u003ch2\u003eRecessed Inner Rings for Warped Records\u003c\/h2\u003e\n\u003cp\u003eTwo recessed inner rings are machined into the underside of the AT628a specifically to accommodate the most common real-world imperfection in vinyl records: slight warping or bulging near the spindle hole. Many records, particularly older pressings, develop a small raised ridge around the centre hole that prevents a flat-bottomed stabilizer from making full contact with the record surface. The recessed rings on the AT628a clear this raised area and allow the outer contact zone of the stabilizer to press down firmly and evenly on the label surface, achieving the clamping effect regardless of minor centre deformation. This is a practical design refinement that makes the AT628a more universally effective than simpler flat-bottomed designs.\u003c\/p\u003e\n\n\u003ch2\u003eNon-Magnetic Design Safe for Phono Cartridges\u003c\/h2\u003e\n\u003cp\u003eThe AT628a is non-magnetic, which is an important specification for a device placed directly above the phono cartridge during playback. Moving magnet and moving coil cartridges are sensitive to magnetic fields, and a ferromagnetic stabilizer could theoretically interact with the cartridge's internal magnetic circuit. The stainless steel alloy used in the AT628a is specifically selected to be non-magnetic, ensuring it poses no risk to the cartridge's output signal, channel balance, or long-term performance.\u003c\/p\u003e\n\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrecision-Machined Stainless Steel:\u003c\/strong\u003e Rigid, corrosion-resistant construction provides even mass loading across the record surface for reduced resonance and improved playback clarity.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003e450 g (15.9 oz) Mass Loading:\u003c\/strong\u003e Sufficient weight to couple the record firmly to the platter, damping resonance without exceeding the bearing capacity of compatible turntables.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTwo Recessed Inner Rings:\u003c\/strong\u003e Underside geometry accommodates records with slight warps or bulging near the spindle hole, ensuring consistent contact across a wider range of pressings.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNon-Magnetic Construction:\u003c\/strong\u003e Safe for use with all moving magnet and moving coil phono cartridges, posing no risk of magnetic interference.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFits Spindles up to 21 mm:\u003c\/strong\u003e Compatible with a wide range of turntable spindle heights across mid-range and premium decks.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eContoured for Easy Gripping:\u003c\/strong\u003e Machined exterior profile allows confident placement and removal without tools.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorrosion and Tarnish Resistant:\u003c\/strong\u003e Stainless steel finish maintains its appearance over years of use without polishing or treatment.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMade in Japan:\u003c\/strong\u003e Manufactured to Audio-Technica's precision standards at their Japanese production facilities.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eTechnical Specifications\u003c\/h2\u003e\n\u003ctable\u003e\n  \u003ctbody\u003e\n    \u003ctr\u003e\n\u003ctd\u003eMaterial\u003c\/td\u003e\n\u003ctd\u003eStainless steel\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eWeight\u003c\/td\u003e\n\u003ctd\u003eApprox. 450 g (15.9 oz)\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eMaximum Spindle Length\u003c\/td\u003e\n\u003ctd\u003e21 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eUnderside Profile\u003c\/td\u003e\n\u003ctd\u003eTwo recessed inner rings\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eMagnetic Properties\u003c\/td\u003e\n\u003ctd\u003eNon-magnetic\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eCountry of Manufacture\u003c\/td\u003e\n\u003ctd\u003eJapan\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eCompatible Turntables\u003c\/td\u003e\n\u003ctd\u003eWide range of mid-range and premium models with spindles up to 21 mm (verify bearing weight capacity with manufacturer)\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eIncompatible Models\u003c\/td\u003e\n\u003ctd\u003eAT-LP3XBT, AT-LPW30, AT-LP60 Series, AT-LP60X Series, AT-LP70X Series, Sound Burger, and all Audio-Technica entry-level turntables\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003c\/tbody\u003e\n\u003c\/table\u003e\n\n\u003ch2\u003eFrequently Asked Questions\u003c\/h2\u003e\n\n\u003ch3\u003eWhat is the Audio-Technica AT628a disc stabilizer?\u003c\/h3\u003e\n\u003cp\u003eThe AT628a is a precision-machined stainless steel record stabilizer from Audio-Technica, made in Japan, that fits over the turntable spindle to hold the record firmly against the platter. It weighs approximately 450 g (15.9 oz), fits spindles up to 21 mm long, and features two recessed inner rings on its underside to accommodate slightly warped or centre-bulging records. It is non-magnetic and compatible with a wide range of mid-range and premium turntables.\u003c\/p\u003e\n\n\u003ch3\u003eHow does the AT628a compare to the Pro-Ject Record Puck E and the Ortofon Weight-It?\u003c\/h3\u003e\n\u003cp\u003eThe AT628a sits in the same category as the Pro-Ject Record Puck E and the Ortofon Weight-It but differentiates itself through its stainless steel construction and recessed inner ring geometry. The Pro-Ject Record Puck E uses aluminium and weighs approximately 180 g, making it a lighter option suited to turntables with modest bearing capacity. The Ortofon Weight-It is also aluminium at around 430 g and lacks the recessed underside rings. The AT628a's stainless steel alloy delivers greater density for its size, and the two recessed inner rings address real-world record imperfections that flat-bottomed stabilizers handle less reliably. For turntables rated to accept the load, the AT628a offers a more complete solution.\u003c\/p\u003e\n\n\u003ch3\u003eWhich turntables is the AT628a NOT compatible with?\u003c\/h3\u003e\n\u003cp\u003eThe AT628a should not be used with the Audio-Technica AT-LP3XBT, AT-LPW30, or any turntable in the AT-LP60, AT-LP60X, or AT-LP70X Series, nor with the Sound Burger portable turntable or any other Audio-Technica entry-level model. These decks are not designed to support the 450 g mass of the AT628a at their platter bearings. For any turntable outside the Audio-Technica range, the manufacturer should be consulted to confirm the bearing is rated to carry the additional load before the AT628a is used.\u003c\/p\u003e\n\n\u003ch3\u003eWill the AT628a affect my phono cartridge?\u003c\/h3\u003e\n\u003cp\u003eThe AT628a is non-magnetic and poses no risk to moving magnet or moving coil phono cartridges. The stainless steel alloy used in its construction does not generate or distort magnetic fields, meaning the cartridge's output level, channel balance, and internal components are unaffected by the stabilizer's presence directly above during playback.\u003c\/p\u003e\n\n\u003ch3\u003eDoes the AT628a work with warped records?\u003c\/h3\u003e\n\u003cp\u003eThe AT628a improves playback on records with minor warps or a slight bulge near the spindle hole. The two recessed inner rings on its underside clear the raised centre area that prevents flat stabilizers from seating properly, allowing the outer contact zone to press firmly and evenly on the label surface. For severely warped records with significant dish warp across the playing surface, a stabilizer alone cannot correct the deformation and a record flattener would be the appropriate remedy.\u003c\/p\u003e\n\n\u003ch3\u003eWhere can I buy the Audio-Technica AT628a in Toronto or Canada?\u003c\/h3\u003e\n\u003cp\u003eThe Audio-Technica AT628a Stainless Steel Disc Stabilizer is available at Vinyl Sound, an authorised Audio-Technica dealer in Toronto, Canada.
