Overview

This unit is in excellent condition. It has a couple of tiny marks, please see the pictures.
All accessories are included as new, all still sealed including the tonearm cable.
The internal and external boxes are also included and all internal packaging.

The Series IV precision pick-up arm owes much to the technology developed for the acclaimed Series V. Although presented at a lower price it retains the unique one-piece magnesium tone-arm, dual-lock base and other advanced features listed.

The Series IV is a worthy relative of ‘the best pick-up arm in the world’ with a sonic performance reflecting the care and attention to detail underlying its design and manufacture.

Features

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. 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).
