Solid Copper Armboard

A rigid, solid copper armboard for SME, Jelco, Rega, Linn and other suitable tonearms for Technics SL-1200 & SL-1210 Turntables.

Armboard 630x280

Technical Description

The Arm Plate for the SL1200 is made from solid copper plate, which has been annealed at 600deg C and quenched in an acid bath.

This imparts excellent sonic qualities in respect to it being able to absorb any vibration and harmonics generated by the Tone Arm Column.

The Copper Arm Board can be Machined to fit any Arm configuration, consistent with the arm being able to fit into the SL1200 arm well.

The Arm Board shown is for the SME series of arms.

Arm Boards for Jelco, Rega, etc can be supplied on request.

The three securing holes for the Arm Board are drilled to take 5mm diameter bolts of the user’s choice. Those shown are button-head hex key tensile bolts but theses may not suit all tastes.

This Solid Copper Arm Board is far superior to the very thin two-part devices offered by other suppliers, which are often only secured together by clock-size screws and allow the assembly to vibrate like a diaphragm.

They have absolutely no inherent rigidity when having to span the area of the arm well in the SL1200. Which was designed this way in order to accommodate the excellent VTA mechanism supplied by Technics.
