- The price has been reduced! 2025/4/28 sales price 398,000 yen 2004 version MC275 replica. A power switch and 3P inlet have been added to this model, and the internal design has also been completely renewed. It's easier to use, clear, and has a wider sound field than previous replica models, but the sense of power it exudes is still alive and well. This is a versatile amplifier that can be used not only for jazz but also for classical music. Externally, there is a scratch on the hood cover. Serial JVN1005 (Fujisawa Yukishi) Maintenance information: 2025.4.28 Operation confirmed Accessories: instruction manual, power cord, bonnet Main specifications: KT88 push-pull input 2 systems (XLR/RCA) 75W+75W (4/8/16Ω) mono 150W (2/4/8Ω) W405 x H210 x D305 mm 29.1 kg

- The price has been drastically reduced. 2025/5/5 sales price 698,000 yen Arrived for the first time in about 14 years! An ultra-premium mono tube power amplifier made in France. KT88/6550 push-pull with Class A operation is used as the output stage. You can fully enjoy the rich and sweet tone, the sound unique to vacuum tubes, and the afterglow. As for the exterior, deterioration over time can be seen on the nameplate on the transformer top plate, but it is a relatively beautiful category (Oikawa Tetsuji) Maintenance information: 2021.5.13 Maintained (+500V power supply rectifier diode replacement (8) and power supply fuse (5A) +500V rectifier circuit section voltage division resistor added to the electrolytic capacitor 160 kΩ 3 W x 2. A discharge resistor was added to the +375V circuit for the initial stage power supply, 160kΩ 3W x 1. Operating current measured value on the primary side: 1.55A. Since the power supply SW mounting screw was tightened, the fuse box screw was increased and tightened, and looseness occurred in the chassis bottom plate mounting screw nut caulking part, nut fixing and repair treatment was carried out. In addition, residual noise checks and maximum output sound output tests were carried out. 4 output tubes (A, B, C, D) para push-pull current vanlance status. A: 46.7 mA (at both ends of 1.2 kΩ cathode resistors) and good <---enough for use by Hi-Fi B, C, D: 44 mA (good at both ends of 1.2 kΩ cathode resistors) Accessories: power cable Main specifications: 6550 push-pull 80W W230 x H260 x D580 mm 31.5 kg

- Maintenance was carried out with attention to detail, such as replacing deteriorated parts and completely disassembling VOL and repolishing contacts! A kit model of a power amplifier using a 50CA10 3-pole output tube and an OY15 type output transformer, composed of circuits and parts conforming to the MQ60 type, which has been evaluated by LUXMAN. The sound of a vacuum tube has a sense of volume that seems to meet expectations, and it gently envelops you. The sound, which doesn't require scale, is particularly unique, and the slight thickness that spreads from below the mid-range makes you feel comfortable. There are scratches and dullness on the exterior due to use over time. Serial 574994 (Tomonori Asaine) Maintenance information: 2025.1.18 Maintained (impedance switching SW, gain VOL complete disassembly contact refinement, oxidation and sulfidation prevention grease applied. Vacuum tube sockets, block capacitors, electrolytic capacitors, oil capacitors, SP and RCA terminals, semi-fixed VR, fuse holder replacement. Load test (8Ω load 1kHz 30W+30W), input/output waveform confirmation, sound output check performed) Accessories: none Main specifications: 30W+30W 50CA10 push pull W410 x H160 x D205 mm 13.8 kg

- Maintained! A high output power amplifier representative of the Lux Kit. As with the original, the output tube was replaced with a GE 6550A, and the sound that combines both tasteful luster and strength is attractive. There are scratches and seal marks on the hood (Kojima Yosuke) Maintenance information: 2025.2.21 maintained (all 4 output tubes 6550A replaced, 6AQ8 replaced, 2 RCA jacks replaced, exterior and interior simple board part re-soldering treatment, vacuum tube socket caulking repair) *Other measured output 50W (8Ω) was measured with AC100V Accessories: none Main specifications: mulard type drive circuit adopted 50W+50W W465×H168×D206mm 17kg

- The internal parts have been thoroughly reviewed and brushed up! The main part of the SQ38F is an independent power amplifier, the famous MQ60. The natural, smooth sound quality with a high sense of transparency is attractive. You can relax and enjoy classical music and vocals in a natural way. The deep sound quality that cannot be expressed with the latest vacuum tube amplifiers is exceptional. Rust and paint peeling can be seen on the exterior. Serial 812212 (Fujisawa Yukishi) Maintenance information: 2024.11.24 Maintained (vacuum tube socket, block capacitor, electrolytic capacitor, oil capacitor, SP and RCA terminals, semi-fixed VR, fuse, spark killer, diode, micro SW replacement. Load tests, input/output waveform checks, and sound output checks are carried out.

- Thorough maintenance was carried out, such as replacing capacitors and deteriorated parts! A custom model whose circuit was changed from the original to a non-feedback amplifier. The output drops by 5W+5W compared to the MQ60, but surprisingly, this one has a better amount of noise, and the sound quality is clean. The appeal is that it is easy to grasp the sense of localization. The exterior has a feeling of use such as dullness. Serial 40401535 (Tomonori Asaine) Maintenance information: 2024.10.27 Maintained (vacuum tube socket, block capacitor, electrolytic capacitor, oil capacitor, SP and RCA terminals, semi-fixed VR, fuse, spark killer, diode, micro SW replacement.
