Turntable Fischer MT-6225

The Fischer MT-6225 semi-automatic turntable I ordered from HiFiStereo.nl is same the turntable wich I listened and loved from 1978 to ±1990, I then gave it away, LPs and all, to a friend ... stupid, stupid ... I still regret it.

Fisher was part of Sanyo, later Panasonic. Quality audio, as this sleek semi-automatic turntable shows. It is equipped with a Shure V15III element, which stylus can be improved with an hyper-eliptical needle. After more than a year I could pick up the serviced record player in Woerden. Unfortunately it turned out that it did not transmit a signal on one side and another element with a new needle was placed (AT-130e).

I connect the record player to a Phono preamplifier (Tonar Vinyline MM/MC €150) that I ordered with it.

Unique linear motor drive system
The Fisher MT-6225 direct drive turntable employs a very unique linear motor drive system, very different from some of the other direct-drive turntables on today's market. If a comparison is made, the most obvious difference is the utmost simplicity of the MT-6225, and since this is an electromechanical device, simplicity translates into long-term stability and reliability.

Some of the most outstanding features of this unique drive system are that the turntable platter is the rotor of the motor, that there are no electrical connections to the rotor, that the rotor has no armature windings and that all the complicated electronic circuitry is in a stationary (non moving) position on a single PC board mounted into the turntable base.

Fisher MT6225:  A Major Technological Advance in Turntable Engineering

The worlds first linear motor direct drive turntable

One of the problems in improving turntable performance, especially with direct drive systems, is the difficulry of reducing woa and flutter due to cogging action of the direct drive motor.
With its limited number of poles (usually 12) , a conventional direct drive system has an inherent problem, at its relatively slow operating speed, of low starting torque.
To solve these problems and improve turntable performance, Fisher has engineered the linear motor, 120 pole direct drive systems.

The Platter is The Motor
In effect, the platter becomes the motor of the MT6225. and Fisher's 120 pole design practically eliminates cogging action and wow and flutter - to a totally inaudible 0,03%
And the linear motor direct drive system further reduces turntable rumble to an extremely low -70 dB, so far below hearing level to be completely inaudible.

How it works
A continuous ring of magnetic material, containing, 120 magnetic poles, is attached to the inside bottom rim of the platter. As the platter rotates, each pole opposes one of the electromagnetic drivers on the base top. Each of the 120 poles is attracted or repelled as it passes the driving electromagnets for smooth, stable operation.

An electronic sensing device monitors the platter's speed, and acts as a servo feedback control to maintain practically perfect speed accuracy. A built-in strobe and pitch controls are provided. The speed accuracy of the system is independent of line voltage fluctuations.

The Arm
The handsomely styled Fisher MT6225 is equipped with a professional type horizontal and vertical gimbal suspended tone arm for performance commensurate with its technologically advanced design.

The arm accepts all standard cartridges. The auto-return system which returns the arm to rest at the end of a record is also an advanced design with no restraints on its lateral or vertical motion during operation.

The arm has adjustable tracking force with calibrated settings from 0,6 to 3,5 grams. There's also precise variable anti-skate, and viscous damped cueing. The MT6225 also has an aluminum alloy die cast platter, and a walnut grain vinyl veneer wood base.
