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.
• 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.
