Fisher MT 6250, upgrade?

Ciao a tutti.

Io ho ereditato da mio padre questo giradischi. E' in ottime condizioni a parte due segni sul coperchio assolutamente trascurabili.

Secondo voi vale la pena investirci un po' nella testina e magari far sostituire il cavo si segnale?

E' un bel giradischi? Ditemi pure la verità. Io lo tengo per valore affettivo, ma vorrei capire a che livello è. So che era il top di gamma, ma non so quanto sia valida la gamma :P

Grazie,

Mattia

Model MT 6250 TURNTABLES

Description

The Fisher MT-6250 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 Fisher MT-6250; 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.


The linear motor used in the MT-6250 moves and accelerates upon the
application of a 3-phase drive signal at a frequency of either 33 1/3 Hz
or 45 Hz to 3 stator field coils. The 3-phase drive signal produces a
progressively changing magnetic field in the stator windings. This
magnetic field will attract and repel (or pull and push) the respective
magnetic poles of the rotor magnets and thus cause the platter to
rotate.


Inertia causes the rotor to turn past the exact position of North
Pole and South Pole alignment, and at this instant the magnetic field
advances or rotates, thus pulling and pushing the rotor again in the
same direction.
