• Unique one-piece pressure die-cast tone-arm utilising the advantages of magnesium, replaces conventional fabricated construction.
• Internal constrained layer damps minute residual vibration leaving the tone-arm acoustically inert.
• Fine machined cartridge platform, enamel free to avoid interface resonance.
• Stainless steel cross shaft, ground and thread ground. Carried in massive yoke on 10mm ABEC 3 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 ABEC 7 ball races, widely spaced to resist tilt.
• Anti-skate control operates through tension spring and filarnent. Dial corresponds with VTF and haspositive 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. Adjustment leadscrew journalled in twin ball races with lever clamping.
• 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.
