ADDITIONAL INFORMATION

BUILD

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.

DAMPING

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

ADJUSTMENTS

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. Adjustment leadscrew journalled in twin ball races with lever clamping.
Fine adjustment of horizontal tracking angle (HTA).
