SME Model 3009 Tonearm
A knife-edge bearing, a wood-lined stainless tube, and a tracking-force scale good to a quarter gram - the arm that made British precision a selling point in American listening rooms.
Overview
The Model 3009 is a pickup arm for 12-inch records. It was sold in the United States through Shure Brothers of Evanston, Illinois, and built in England by SME Ltd. of Steyning, Sussex. It arrived at $100.50. The companion 3012, built for 16-inch transcriptions, ran $110.50. The 3009 came complete in the box: one shell, the arm itself, a mounting template, an alignment protractor, and the hardware. A buyer wasn't piecing a tonearm together from a parts list.
The bearing set the 3009 apart. SME used a virtually frictionless knife-edge design, with pivot friction claimed at less than 20 milligrams in both the horizontal and vertical planes. Owners and reviewers fixate on that number because it is the whole argument for a low-mass, high-compliance setup. An arm that resists movement at only 20 milligrams lets a delicate stylus do its job without fighting the pivot. The arm tube is wood-lined stainless steel, a construction SME says pushes resonances outside the recorded range, keeps their amplitude small, and damps what remains.
The weight system is unusual. SME balances the arm statically both longitudinally and laterally, and the lateral part is the piece most people miss. A rider weight sets tracking force anywhere from ¼ to 5 grams, adjustable in ¼- or ½-gram increments. SME claims the scale is as accurate as a fine stylus pressure gauge. If the scale holds, you don't have to drag out a gauge every time you swap cartridges.
Adjustment is where the 3009 earns its reputation. The sliding base offers alignment adjustment through 1 inch, and height adjusts through 34 inch. That is enough range to hit the optimum length, offset, and overhang when set with the included protractor. An anti-skating bias adjuster counteracts the arm's tendency to drift toward the record center and favor the inner groove. A hydraulic, lever-operated set-down lowers the stylus in slow motion onto any part of the record, so cueing needs no hand on the arm.
The smaller details show the designers thought about daily use. The arm rest uses a nylon jaw with a stainless steel locking link. The headshell takes cartridges at standard ½-inch spacing with detachable pillars and mounting screws, and the arm terminates in an international standard 4-pin socket. An output socket and plug give the stiff wiring and the delicate pickup lead a rigid junction, so the cable doesn't influence the arm's free movement.
The period press took the British claim at face value. Audio (August 1965, p.31) noted that the English are famously conservative about advertising claims, then concluded that SME's "best pick-up arm in the world" billing was simply a fact, made, in the magazine's words, by dedicated craftsmen working to extraordinarily close tolerances. High Fidelity (May 1966, p.70) treated the 3009 as a professional tone arm for manual turntables and listed it at $100.50, manufactured by SME Ltd. in Steyning, Sussex.
Later production brought running improvements. A Shure announcement reported three changes to the SME arms: a pre-wired cable and plug assembly for solder-free installation, a 5-lead wiring system with separate hot and ground leads for each channel plus the arm, and arms shipped fully assembled in styrofoam. The 3009 held at $100.50 and the 3012 at $110.50, with pre-cut mounting boards available at $15. The pre-wired, five-lead version is the later spec.
By the 1970s the 3009 had become studio furniture. A Recording Engineer piece on Los Angeles transfer houses describes Technics turntables modified to take SME Model 3009 Series III arms. Engineers added acoustical putty between headshell and cartridge to tame resonance, and ran Stanton 881S cartridges. Another engineer reported good results pairing moving-coil cartridges, Ortofon MC20 among them, with SME arms, chasing the fine detail that a good moving coil pulls out of a record.
For collectors, the 3009 is the entry point to SME ownership and one of the more attainable classic British arms. Check the bearing first, since the whole design rests on that sub-20-milligram pivot. Check the rider weight and its scale, because a missing or damaged weight turns tracking force into guesswork. Check the hydraulic cueing, the part most likely to need attention on a fifty-plus-year-old arm. Exercise the anti-skate mechanism and the sliding base adjustment before purchase. Original boxes, templates, protractors, and extra shells add value.
