RS-28CX £4850

RS-28CX is equipped with the CR type equalizer based on
GE(General Electric/USA) 12AT7 authorized by J.A.N.(Joint
Army & Navy) standard of US Army, and can reproduce a
very high quality and clear sound without adding any NFB.
To
avoid compromising on sound quality ,one of the solutions
we adapted to totally protect the sensitive CR type
equalizer from negative effects was to develop a separate
power supply unit. Likewise, some of the finest available
high-end audio components were selected for the RS28C to
keep the deflection of the RIAA curve below +/-0.3%.
Of
course, the phono equalizer is only one of the strengths of
the RS28C. Another notable feature is a very strong output
voltage created by the Dual-Triode Tube 6CG7 of General
Electric(USA) used for the line stage. Leben further
selected the best quality tubes out of these and
constructed a powerful SRPP type amplification which can
supply power amplifiers with a maximum 80V of clean output
signal. In considering the fact that output voltage of a
standard preamplifier is more or less 40V, the RS28C can
output about two times as much voltage, which will drive
power amplifiers with very low input sensitivity.
Likewise,
for using the RS28C with a high sensitivity power
amplifier, a 5-step attenuator is present in order to
eliminate residual noise from speakers.
Leben
also included two outputs (one fixed and one variable) in
order to cope with requirements for adding a Sub-Woofer.

RS-100
£3150

"GENERAL ELECTRIC"(USA) High Output Tube 6CG7
The
line Amplifier Circuit consists of special selected
Dual-Triode Tube 6CG7(General Electric/USA) by SRPP system
to improve high-frequency range of the sound, and can
supply a strong signal of 52V to the power amplifier.
Hum
Noise Canceller Circuits
For lighting the heater of 6CG7 tubes, DC current(12V) is
applied to minimize the noise of heating, and additionally,
60V bias is applied to the heater to cancel the noise
caused from the heater.
Carbon Film Resistor
Leben dared to choose a custom-made Carbon Film Resistor of
+/-3% error margin to have a more natural and smooth sound
instead of normal Metal Film Resistor of +/-1% error margin
which makes the sound more hard and stiff.
Direct
Input Terminal
A direct input terminal goes directly to the volume control
to transmit a pure signal without passing via the contact
points of the selector switch, therefore, a superior result
is obtained when a phono preamplifier or a CD player is
used through the Direct Input.
**Leben applied for the direct input circuit a highest
audio-grade PCOCC-A shield wire produced by Oyaide Electric
Co to achieve a pure signal transmission.
Luxurious
Employment of highest-grade components
The
highest audio-grade components are used for all essential
parts:
• Super-precision German UXB resistor of 0.1% error margin.
• "EAO"(Germany) MKP Condensor
• "Nichicon" audio-grade condensor "Fine Gold"
• "ALPS" audio-grade volume for Volume and Balance
controls.
• "Spiral Wire" for all inner wiring(very near the single
structural wire)
Other
Features
• Two Outputs: One is Variable(with Volume level) and the
other is fixed.
• Five inputs plus Direct input.
• REC OUT/REC MONITOR IN
• Muting 30 minutes after Power-On.
• Natural wood Side Panels.
