product description:

SME 309 - 9'' audiophile tonearm

The Series 300 broadens the application of SME
technology.

Although the unique one-piece magnesium tone-arm
is used for the Series 300 Model 309, advanced metal techniques
produce a fabricated arm of exceptional stiffness for the Series 300
Model 310 and 312 arms thus allowing a choice of three arm lengths to
suit all decks.

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.
  

  
  

• Anti-skate control operates through tension spring and
  filament. Dial corresponds with VTF and has positive OFF position.
  

  
  

• Lowering/raising control gives smooth positive action. Height
  of lift can be adjusted.
  

  
  

• Dual-lock base provides movement control with high rigidity.
  

  
  

• Tungsten-alloy balance weight carried on damped two-point
  suspension. Extra-low inertia design assists warp riding.
  

  
  

• Underslung weight housing corrects centre of gravity and
  provides non reflective tone-arm termination.
  

  
  

• Swivelling, damped output socket minimises vibration
  transmission in sub-chassis use.
  

  
  

• Reference lines on tone-arm facilitate VTA setting.
  

  
  

• Fine adjustment of horizontal tracking angle (HTA).
  

  
  

• New design alignment protractor sets HTA with great accuracy.
  

  
  

• Cartridge leads and internal wiring LCOFC litz.
  

  
  

• Balanced LCOFC audio lead with gold plated phono plugs.
