The reverse occurs as the stylus moves down the warp and the pitch returns to nominal value. to think through what those implications are and possible mitigation and. The effect is identical to a decrease in turntable speed, and it lowers the pitch of the reproduced signal. Innovative approach to sme financing in nigeria: a review of small and medium. When the axis of the horizontal bearing is well above the record surface (figure 7a), the stylus will move forward simultaneously with its upward movement, and the speed of the record goove relative to the stylus will decrease. As the tonearm moves up and down under the influence of record warps, the stylus moves in an arc. "The height of the horizontal bearing above the record surface is important for reproduction quality. I have one, NOS, and will do a resonance test some time in order to find out if the hinged brush does anything about that.Ī dynamic balanced arm will mitigate against tracking force discrepancy on an unlevel surface.īut if the pivot is appreciably higher than the record itself, there will be increased vertical arm motion (rising and falling) proportional to the distance of the pivot above the record. It might have provided minimal damping, but that was not its main function. The brush rode on a hinge, offset by a 1 gram tracking force increase. Although the Model 20/2 turntable is available a la carte for 9,999 it’s also sold with SME’s.
#MITIGATING SCRATCH ON SME TONEARM SERIES#
And just to be sure, Robertson-Aikman still personally inspects every Series 309, IV and V tonearm, and every turntable that goes out the door with the SME logo on it. The information about Stanton (Pickering) is, unfortunately, the case. Even the screws and grommets used in the tables are made in-house. I know JICO offers replacement styli for the V15, with a brush, but I do not know whether the brush they use is actually damped, or just hinged. Mid-price SME comes complete with cost-cut alu- minium armtube and. now my WFH office/mancave Originally built from spare parts around 2000 or so. Second Linn LP12 : in what used to be my parents' house. Unfortunately, after time in service the damping material (not sure what was used) could dry out, making it useless for the intended purpose. Not really what it appears, with a curious tone arm and bluffly simple yet FREE. The motor and PS have been changed, tone arm changed to SME 3009 S2 Improved, mainly Shure V15 Type3, occasionally a London Decca V on SME headshell. They advertised it using the Denon DL-103D, as an example of a cartridge that might benefit from its action. An outrigger device attached to the headshell screws. Discwasher company marketed a device called the Disctracker that applied damping (I think pneumatic) to the headshell, riding just in front of the stylus assembly.
