For use with Premotec and Airpax, 9904 111 series motors are used in Linn, Rega, and Nad Turntables.
Made from 3.2 mm thick sound-absorbing material which exhibits good chemical stability, cut to the same dimensions as the motor. The modification barrier absorbs much of the vibrational energy produced by the motor and dissipates the energy stopping the vibration from resonating through the turntable plinth and into the signal path.
Unbolt the motor and sandwich the barrier between the motor and the chassis. The isolation barrier has good compression performance and will reduce in size once bolted into place (acts like memory foam). One side of the barrier has a tacky surface so alignment is easier before installation. They are now supplied with a larger hole so there is no need to remove the pulley to install the barrier.
In some circumstances the motor pulley height may need to be adjusted, this is usually a swift and easy process. However, through research, this hasn't been an issue.
Supplied with a nut and bolt kit containing lock nuts. The locking nuts prevent from applying too much pressure to the barrier and will never loosen under vibration from the motor.
