The Woodpecker is the entry level model and incorporates motor, bearing and armboard in a solid and fairly substantial slab of plinth, with aluminium facing top and bottom.
Interior construction uses constrained layer damping, a technique of combining different materials to combat resonance. It may not look it, but the turntable’s plinth is made from laminates that consist of aluminium and tempered MDF; that is MDF that has been heat-treated prior to lamination. The whole sandwich is then machined and given a Delrin (acetal plastic) surround.
Atop the laminations mentioned there is an anti-resonance ‘circuit’ made of an unspecified, but apparently significant type of steel. This also supports the platter’s bearing.
