ACRYLIC ARM BOARD & stainless steel screws

Our acrylic arm boards are machined here in the UK from premium cast acrylic. Acrylic is an inert material and has superior sonic qualities than wood.

The standard acrylic arm board (this listing) has tapped holes for the sub-chassis connection. The acrylic thread is strong and perfectly fine and more durable than the threads in the wooden board. I can supply acrylic arm boards with a brass threaded inserts for a superior connection. The cost of this is an additional £4.50

ACRYLIC CROSS BRACE 

When vibrations enter an electrical component it generates electrical noise, the term used to describe this is Microphony. One of the most vibration-sensitive components is the crystal on your LP12 power supply, and this component is crucial to delivering uniformed torque from the motor. The standard 1.2 mm thick steel cross brace that the PSU is attached to is rife with vibrations from the platter and motor.

Introducing the Serene cross brace, an extremely inert platform to empower your power supply to perform at its best.

The cross brace is machined here in the UK from a particularly rigid cast acrylic which won’t distort when tightened. Due to its composition, it’s also extremely inert. To supplement the seating of the acrylic, we use rubber mounted studs to mount the PSU to eradicate any remaining vibration entering the power supply. This simple and easy to install upgrade offers surprisingly impressive improvement in the musical qualities of your LP12.


  • Compatible with Valhalla, Lingo , Hercules power supplies and others.
  • The simplistic design means attaching and detaching your power supply is simple.  No longer do you have to deal with the annoying plastic PCB pins. 
  • The board eliminates vibrations from entering the sensitive power supply.
  • Precision machined here in the UK from a premium 8mm thick cast acrylic billet.
  • A straightforward replacement for the original Linn cross brace.
  • Comes with all necessary screws, nuts, cable tie and washers to fit it to your LP12 and PSU
