The Series 300 broadens the application of SME technology.

One piece magnesium tone arm, available as Model 309 and Model 310.

The detachable magnesium headshell has a new style coupling, providing the convenience of rapid cartridge interchange without loss of rigidity.

Our designers can be justly proud of these models which offer a performance and manufacturing excellence unmatched by many more expensive models.

Unique pressure die-cast magnesium shell detachable and interchangeable without disturbing cartridge or wiring.
New design clamping arrangement ensures rigid junction with tone-arm.
Internal constrained layer damps minute residual vibrations making tone-arm acoustically inert.
Stainless steel cross shaft, ground and thread ground. Carried in massive yoke on 10mm precision ball races. Axis at record mean level to minimise warp-wow.
Unique assembly gives high rigidity and allows bearings to be critically adjusted before tone-arm is fitted.
Stainless steel vertical shaft, ground and thread ground, with integral 16mm diameter flange to couple shaft and yoke.
23mm diameter steel pillar, heat treated, ground and honed, carries two 17mm precision ball races, widely spaced to resist tilt.
