"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-frequecy range of the sound, and can supply a strong
signal of 52V to the power amplifier.
* RS-100(U) is equipped with
12AU7A instead of 6CG7 to create the sound of different characteristic.
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 cancell 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
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 contact
points of the selector switch, therefore, it makes a superior result
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 acheave a purest
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 Level Volume) 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.
