||PL-1400: 67,000yen(1974 release)
A DC servo DD motor and the record player using a
high-sensitivity S character type pipe arm.
There were two kinds, PL-1400
the cartridge was attached to, and PL-1400C to which a cartridge is not
The actuator has adopted the direct-drive scheme and is
driving the high heavy weight class turntable of a flywheel effect using a
super-low-speed brushless DC servo motor on the motor.
electronic formula control circuit which consisted of a transistor and diode is
adopted as a control circuit.
The automatic control (servo) of the
rotational frequency which this set up once was carried out, and the fixed
rotation has been obtained regardless of the variation of an off-site
temperature or supply voltage.
It is 33, looking at the stroboscope minced
by the turntable for the change of a velocity with the pure electronic formula
which can be held by the constant change of an electronic circuitry. 1 / 3 or
45rpm all can perform a velocity fine tune independently in ±2% of within the
limits. Moreover, since AC power supply is changed into a direct current by a
voltage stabilizer and the motor is driven, there is no time and effort of
exchanging pulleys for every line frequency.
S character type tone arm
of a new-installation meter is adopted as a tone arm.
The cartridge to Self-weights 4g-32g is attached without a sub wait, and the difference signal component of a very light stylus-force performance or a discrete 4ch scheme which is 0.5g can also be traced.
Moreover, a head shell gives a rubber cushion specially and
is reducing a vibration and modulation distortion with the lightweight type.
The cabinet is the vibration proof strengthening cabinet made into the
double structure combining the metal base and native wood. This reduces an
extraneous vibration and the oscillation from a floor, and the howling is
Moreover, the large-sized insulator which can adjust the degree
of level of the main unit of a player is adopted.
PC-330E which is
man-month type cartridge is attached to PL-1400.
A 0.2x0.7mil ellipse type
electric-contact-point diamond stylus is adopted as the needle point, and the
tone-quality modification is aimed at by the weight saving (effective mass of
0.55mg) of this and vibration system.
Moreover, a perpendicularity and a
horizontal can also trace the perpendicular swing of a matrix 4ch record by
