Description

Description Attention!! This device is designed for Japanese power specifications (100V, 50/60Hz). When using it, adjustments may be necessary to match the voltage of the country you are in. Please ensure you provide a suitable transformer for your specific country. Using the correct voltage will allow you to operate the device safely and effectively. ■ Features Luxman and the history of vacuum tube products Luxman, founded in 1925, has been making vacuum tube amplifiers continuously since the launch of the vacuum tube integrated amplifier SQ-5A in 1961. Among them are models that are highly regarded as "masterpieces," and many of them are still in active use decades after their release. The CL-38uC and MQ-88uC are the culmination of Luxman's wisdom and know-how cultivated through its history and tradition of vacuum tube amplifier manufacturing. High-end quality parts: a sign of high quality Vacuum tube amplifiers have a simple circuit configuration, so the quality of each part has a significant impact on sound quality. The CL-38uC and MQ-88uC are made with Luxman's unique high-quality parts, such as transformers and block capacitors. In addition, to accompany the customization, we adopted high-voltage metallized polypropylene film capacitors made by Nichicon for the coupling capacitors, achieving a more natural and smooth tone. Reproduction design from the heyday of vacuum tubes The CL-38uC and MQ-88uC are vacuum tube amplifiers using the latest technology and design, but their exterior designs are a universal interpretation of models from the heyday of vacuum tubes (the CL-38uC is inspired by the CL-35 released in 1970, and the MQ-88uC is inspired by the MQ-60 released in 1969). The classical design exterior is easy to use with knobs and lever switches that pursue "beauty of utility," and high sound quality is achieved by shortening the internal wiring. You can enjoy the nostalgic traditional design and modern high performance at the same time. Long life, high reliability, and reliable long-term support The CL-38uC and MQ-88uC are subjected to a 48-hour aging process after the product is assembled and then final performance check is performed. All vacuum tubes are made by JJ (Slovakia), which has a reputation for quality. The stability of the circuit has been further improved. The long-life design allows for ample operating voltage and heat dissipation for the vacuum tubes. In addition to a thorough support system that continues to maintain products that have been on the market for more than several decades, the premium extended warranty system extends the free warranty period to three years (one year for vacuum tube parts). You can use it with peace of mind for a long time. Output stage with JJ KT88 The output tube of the MQ-88uC is the KT88 made by JJ (Slovakia), which is well-known for its powerful and thick tone. The triode connection extends the life of the vacuum tube and achieves a smooth and transparent tone that is characteristic of vacuum tube amplifiers. The first stage is parallel connected, and the driver stage is equipped with the proven Mullard circuit. The final stage uses a push-pull configuration that is compatible with the Mullard circuit, achieving 25W+25W (4, 8, 16Ω) power and low distortion amplification. Independent speaker terminals for 4, 8, and 16 ohms The MQ-88uC is equipped with independent speaker terminals for 4, 8, and 16 ohms, which are effective in matching with speakers to bring out the speaker's inherent potential. This realizes music playback with less distortion and a sense of power. The MQ-88uC also features a direct input mode in which the signal bypasses the volume, and a variable (volume adjustable) input mode that allows direct connection to source devices such as CD players. OY15 type output transformer and power supply In vacuum tube amplifiers, the output transformer plays an important role in determining the sound quality and performance. Luxman has redesigned and reproduced the OY15 type output transformer in an aluminum die-cast case that was installed in the classic models of the past in an original shape. In addition, the power supply unit, which combines an EI type transformer, which is characterized by its tenacious sound quality, with a block capacitor, has a high inertia configuration and achieves excellent drivability. New high-quality dark brown exterior color The base color of the MQ-88uC has been changed from the black of the previous model MQ-88u to a dark brown color that matches well with the wooden box and adds an attractive touch to the device's exterior. It harmonizes with the aluminum top panel with a silver hairline finish and the aluminum die-cast power transformer case with a matte black coating to create a high-quality, beautiful appearance. ■ Specifications 〇 Rated output 25W + 25W (4Ω, 8Ω, 16Ω) 〇 Input sensitivity 890mV / 25W 〇 Input impedance 32kΩ 〇 Frequency response ・ 20Hz to 20kHz (+0, -0.2dB) ・ 10Hz to 100kHz (within -3.0dB) 〇 Total harmonic distortion ・ 0.1% (1kHz / 1W) ・ 0.5% (20Hz to 20kHz / 1W) 〇 S/N ratio (IHF-A) 105dB 〇 Circuit type Driver: Mullard circuit, Output: Triode connection 〇 Vacuum tubes used ECC83S x 2, ECC82 x 2, KT88 x 4 〇 Power supply voltage AC100V (50 / 60Hz) 〇 Power consumption ・150W (based on Electrical Appliance and Material Safety Law) ・ 140W (no signal) 〇 External dimensions 440 (width) x 184 (height) x 230 (depth) mm Depth includes 17mm front knob and 28mm rear terminal 〇 Weight 16.1kg (main unit), 18.8kg (standard packaging) 〇 Accessories Power cable (JPA-10000i: with polarity mark) 〇 Speaker terminal compatible Y-lug terminal dimensions a part width: 14.5mm or less b part width: 7.5mm or more ※Depending on the shape of the Y-lug terminal, it may not be possible to attach it. ※Specifications and appearance are subject to change without notice. ※The power cable included with this product has been changed from JPA-10000 to JPA-10000i.
