Luxman CL-38uC Tube Preamplifier

The Luxman CL-38uC control amplifier bridges traditional analogue heritage with contemporary connectivity. Housed in a classic wooden outer case measuring a standard 440mm width, this unit stands out among high-end tube preamplifiers by offering detailed playback with authentic valve warmth.

Refined Circuitry for Pure Signal Transmission:

At the heart of the design is SRPP (Shunt Regulated Push Pull) circuitry applied across all stages, including the tone control and phono equaliser sections. This layout delivers a flat frequency response, low distortion, and a low output impedance of 300 ohms. Custom Nichicon high-voltage polypropylene film capacitors and shortened internal wiring paths ensure that subtle musical nuances remain completely intact.

Versatile Vinyl Playback and Control:

Dedicated to vinyl enthusiasts, the integrated phono equaliser features independent left and right step-up transformers for moving coil cartridges. A front-panel lever switch lets you adjust between high and low MC impedance to suit your cartridge precisely. Three-position switchable crossover frequencies for both bass and treble allow you to fine-tune the acoustic response to match your listening room or source material.

Shielded Build and Balanced Connectivity:

To prevent magnetic interference, the internal chassis acts as a fully shielded metal enclosure housing a toroidal power transformer and choke transformer. Dedicated balanced input transformers ensure clean integration with modern source components. Every unit relies on JJ Electronic valves, selected for operational stability and subjected to a 48-hour burn-in process before final testing.
