The CL-40, tube
Represents Lux's long-cherished
concept in tube technology to seek for not "sound" but
"musicality". Exclusive Lux design by means of pure
aluminium front-panel, specially turned knobs, and genuine rose-wood
case of glossy urethane finish.
An optimum operational point is
determined by an ideal circuit employing the twin triode 12AX7A/7025.
The "hunger" circuit at the 1st stage combined with
S.R.P.P. (Shunt Regulated Push-Pull) circuit at the output stage
makes it possible to reproduce even the atmosphere of concert hall.
2-Stage Differential Flat Amp
with Tone Control
The twin triodes 6BK7B/7028 and
6CG7/7026 composing 2-stage direct-coupled differential amp offer
utterly unconditional stability in operation with a small amount of
NFb, and removal of the time constant circuitry makes it possible to
amplify even ultra low frequencies down to DC area, thus avoiding
harmful IM distortion. While Lux's acclaimed NFb tone control
provides natural, smooth tonal adjustment.
The twin triodes 12AU7A/7030 and
12BH7A/7032 driven under cascade amp configuration with optimum NFb
amount realizes truly tight bass and transparent treble frequencies.
