Luxman CL-38uC
A vacuum tube preamplifier using SRPP circuitry throughout for low distortion and rich tonal balance
Overview
The Luxman CL-38uC is a vacuum tube preamplifier manufactured entirely in Japan. It features both balanced XLR and unbalanced RCA inputs, with two cinch (RCA) outputs that support bi-amping setups. The unit includes a phono stage for MM and MC cartridges, with specific input sensitivity and impedance settings for each. Designed with a hand-made aesthetic that echoes classic 1970s hi-fi styling, it visually and technically pays homage to Luxman’s 38-series heritage.

Design
The Luxman CL-38uC uses SRPP (Shunt Regulated Push Pull) vacuum tube circuitry throughout all stages, contributing to low distortion and an exceptionally rich tonal balance. The unit is manufactured entirely in Japan and features a hand-made design with vintage case work that reflects the aesthetics of hi-fi's golden age.
Context
The CL-38uC is part of a system pairing commonly used with the MQ-88uC power amplifier, forming a high-end vacuum tube amplification chain. It is considered a modern homage to Luxman's classic 38-series preamplifiers.
