Thorens TD 907 Turntable (Zebrano)

Description

THORENS TD 907

THE ULTIMATE SUB-CHASSIS TURNTABLE

TRADITION REINTERPRETED

The sub-chassis is made of
triCom, an aluminum/POM composite characterized by excellent damping properties
and high stiffness. Its weight has been optimized for high performance. To
reduce vibrations, the synchronous AC motor is mounted directly onto the damped
sub-chassis. It drives the sub-platter via a machined precision belt.

The sub-chassis is suspended by
means of three conical springs which can be adjusted from above in order to
achieve uniform tension. The bearing is made of sintered bronze with a Teflon
thrust pad and optimized for smooth running. The steel axle supported therein
provides very low, constant friction and thus presents a uniform load to the
motor. Two of the turntable’s three feet can be levelled from above, which
facilitates setup.

Depending on the model,
different damping architectures, tonearm boards and platters are used. The
design can accommodate a wide variety of 9″ and 10″ tonearms also
from third-party manufacturers.

SPECIAL FEATURES

Newly developed, ten-step
adjustable pneumatic damping architecture

A conical polypropylene membrane
under the platter bearing is decoupled from the triCom base via a
visco/propylene layer. The air chamber thus formed under the membrane vents
into ten apertures in the base plate which can be opened or closed with a
slide.

Turntable feet with triCom and
viscose foam insert, adjustable

The tonearm board is also made
of triCom and can be cut for almost any 9″ and 10″ tonearm at the
factory.

Three-part platter

The polished aluminium platter
features an acrylic insert that acts as a damping pad for the grooved area of
the record.
