G 1260 R Turntable
A high-quality turntable for the R-series of equipment has long been right at the top of our customers’ wish list. And here it
is: unique in design and quite superb in its sound quality. As with the whole of the R-series, our developers have invested
tremendous time and effort in this project.
Turntables are extremely sensitive mechanical playback systems, and this makes it essential to reduce all external mechanical
and electrical influences as far as humanly possible. For this reason T+A approached this development from two directions:
the one aiming to produce a totally constant, smooth-running drive motor, the other attempting to avoid structural sound,
resonance and vibration throughout the system.
The power unit we employ is a high-quality synchronous motor fitted with a precision-machined pulley, driving the turntable
platter by means of a special rubber belt. This is an excellent solution which can be found in many High-End turntables.
However, T+A did not stop there: instead we decided to tackle the problem of uneven motor running right at its root: over
the last few years we have gathered a tremendous wealth of experience in using DSPs to control complex processes, so
the T+A developers came up with the ingenious idea of optimising the motor coil voltage curve using a DSP, with the aim
of producing a motor which runs so totally evenly and smoothly that there is not the tiniest hint of jerkiness or vibration.
The heavy turntable also starts into motion smoothly and evenly, with controlled torque transfer. Motor speed fluctuations
are simply immeasurable, and this completely eliminates all the problems associated with unregulated drive motors. In
conventional systems the motor speed is inevitably dependent upon mains frequency and voltage, but the T+A design eliminates this problem! And DSP motor control also offers yet another major advantage: since the motor’s rotational speed
is controlled directly, there is no need to change the belt position when selecting the two available speeds (33 and 45 rpm).
The turntable’s mechanical sophistication and case design are just as advanced as the electronic system, for they are also
required to satisfy the most exacting requirements. Judder and vibration have an extremely serious adverse effect on sonic
quality, and for this reason the G 1260 R is based on an extremely massive MDF case; this material has excellent damping
qualities, and the case encloses all the sub-assemblies, with four shock absorbers supporting the main body. The external
aluminium components are of composite sandwich construction, which is highly effective at damping structural sound,
while the aluminium cover is glued to the main body in order to suppress and absorb vibration and resonance effects.
The heavy pressure-cast disc platter is produced using a very accurate machine tool; it is machined to tight tolerances,
and mounted on an aluminium inner plate for de-coupling purposes. The friction of the large support area de-couples the
platter perfectly, and eliminates all traces of structural sound. A thick layer of soft silicone rubber not only avoids damage
to discs, but also provides further damping of structural sound. The platter is acoustically dead, and as such provides the
best possible basis for the pick-up system to track the disc smoothly. The aluminium platter is produced to such extreme
standards of precision that the latest automatic CNC machinery is the only method of making it, not least because it is
precision-turned a second time after the platter spindle has been pressed-fitted! This final process ensure total accuracy of
the whole system. The tolerances for the bronze plain bearing and the hardened and polished steel spindle are held to 5 μm.

As an option we can supply superb phono pre-amplifier modules
based on our proven PH 2000. The module is installed precisely where
it belongs, namely right at the tone arm output. This arrangement
completely eliminates induced interference affecting the extremely
sensitive output signals of the pick-up system. Extremely low levels
of background noise and interference are assured by the mains power
supply section with its sophisticated stabilisation measures, a unique
circuit topology developed specifically for MM or MC cartridges, and
extensive shielding. A set of integral DIL switches allows the PH-G10
MM / MC to be matched perfectly to the pick-up system in use.
We supply the G 1260 R with a high-quality tone arm which is made
for us by REGA. The internally damped aluminium arm itself is produced in a single process using the pressure-casting process, while the
counterweight is made of non-magnetic stainless steel. The high specific
density of stainless steel produces an extremely small but very heavy
counterweight, and this minimises the leverage forces acting on the tone
arm. Upon request we are able to supply the G 1260 R already fitted with
the outstanding Ortofon 2M bronze moving magnet pick-up cartridge.
Special accessories include a plug-in protective cover (H 1260) made
of clear acrylic, and a disc brush (PB 10) made of solid machined brass.
The brush element is made of genuine horse-hair, is very carefully
balanced and effectively removes dust particles without damaging the
disc surface. The disc stabiliser weight (AG 10) is also turned from
solid brass and weighs 650g; it ensures that the disc is perfectly located.
