TT-12 TURNTABLE

TT-12 turntable has two equal mass aluminum platters rotating together.

The two platters are fixed to a high mass aluminum axle.

The result of this design is a platform, particularly isolated from environmental and mechanical noise, while maintaining stability.

An external low noise stabilized power supply feeds a quadrature oscillator and two power amplifiers.

The mains power is rectified, smoothed with oversized capacitors, stabilized with two SMPS at 150KHz and then stabilized again by three separate circuits.

The three clean output voltages are stabilized to 0.1VDC and supply the two power amplifiers and the quadrature oscillator.

The outputs of the power amplifiers, provide two sinusoidal signals and drive the two motors.

Specially shaped aluminum pulleys, rotate the below platter with two belts.

A precision ruby bearing, provides smooth rotation and maintenance free.

 

TA-12 PARALLEL TRACKING TONEARM

In pivoted tonearms, the arm is moved in an arc across the record surface, so the stylus following the record groove has tracking errors.

The arm of the TA-12 moves tangentially to a linear path.

The cartridge moves parallel to the groove, following the same path as the cutting head did when making the record.

Cantilever and stylus are perfectly aligned.

No side forces are generated and anti-skating compensation is not required.
