Decoupling the E50

Thorens TD-124

Decoupling the E50 motor of the Thorens TD124

Ever since the appearance of the TD-124, people have been engaged in endeavours to “silence” the motor. The first serious attempt was by Thorens own engineers by means of the double suspensionrubbers.

Recently the members of the Audio Team (H.A.T) developed a spring modification for any TD-124, which offers a dramatic improvement over any decoupling solution so far.

Apart from taking the motor out of the turntable altogether which, of course, is turning system integrity upside down .

Below you see pictures and measurements of four different versions of motor decoupling.
