Luxman CL-38uC Vacuum Tube Stereo Preamplifier 

The CL-38uC uses SRPP (Shunt Regulated Push Pull) circuitry for all stages to achieve the highest sound quality possible.A genuine phono equalizer is included, the MC-low and MC-high impedance (gain) inputs each have independent MC transformers and are selectable using the MC impedance lever switch.Tone controls enable the listener to fine tune the sound quality.Refined exterior design and newly added balanced inputs make this vacuum tube control amp a new standard for its generation.

LUXMAN's vacuum tube amplifier legacy

Since the launch of our SQ-5A vacuum tube integrated amplifier in 1961, we have continued making vacuum tube amps without a break. We have produced many models that are highly valued as signature models and satisfied music lovers are enjoying them to this day, even several decades after their release. The CL-38uC and MQ-88uC combine LUXMAN's history of producing fine vacuum tube products and the traditional wisdom and skills gained along the way.

The essence of high-end products:
selected high quality components

Due to their relatively simple circuitry, vacuum tube amplifiers are greatly affected by the quality of individual components, hence we utilize LUXMAN's own high-quality transformers and blocking capacitors. Further customization comes in the form of Nichicon made, high voltage, metalized polypropylene film coupling capacitors, which have been introduced for their supple, natural tone. Improved audio quality has been realized by shortening the internal wiring.

Reviving designs from the golden era of vacuum tube amplifiers

The CL-38uC control amplifier and the MQ-88uC power amplifier are based on the latest technology and design, but the exterior styling evokes a classic image from the heyday of vacuum tube audio products. The CL-38uC is modeled on the CL-35, released in 1970, and the MQ-88uC is modeled on the MQ-60, released in 1969. A classic front panel design should be functional, but also beautiful, achieved by careful selection of knobs and lever switches. Listeners can appreciate such traditional design features, with their nostalgic flavor, whilst enjoying these contemporary, high performance audio products.

Long life and reliable design

Each CL-38uC control amplifier and MQ-88uC power amplifier undergoes a final performance check after a 48 hour aging process following assembly. We have selected JJ Electronic (Slovakia) vacuum tubes for these models as they are renowned for their reliability, long life and the ease with which they operate at vacuum tube amplifier voltages and heat dissipation conditions.
