- Maintained! This vacuum tube power amplifier is a complete kit with a focus on parts one by one. The sound coming out of carefully selected parts such as the VT-52×2 made by NATIONAL UNION (WE print on the base is a reprint), Hashimoto transformer H-20-7U, PT-240, CC-10-200W, etc., has a wide range, and is a clean, clear sound with a good sense of touch. Minor scratches can be seen on the front. (FUJISAWA KOSHI) Maintenance information: 2025.4.22 Maintained (insulator rubber replacement. SP terminal looseness correction. Vacuum tube pin cleaning. Check the volume and switches. Hum balance adjustment The operation of the bias meter has been confirmed.) Accessories: power cord Main specifications: used transformer Hashimoto H-20-7U, PT-240, CC-10-200W vacuum tube VT-52 x 2 (NATIONAL UNION) 5Z3 (RCA) 310A large punch x 2 (WE) W450 x H290 x D270 mm (actual measurement including protrusions) output approx. 2 W (at 8 Ω load) input impedance 100 KΩ input sensitivity 0.7 V residual noise 0.5 mV or less

- The TU-8600S, the third generation of the TU-8600 series, has arrived. An R core transformer was adopted for the power transformer, and a “new active motorcycle ass” system was adopted for the 300B bias, and it was developed with the 300B driving in mind. There are no noticeable scratches, there are notes in the manual (Daiki Goto) Maintenance information: 2025.4.17 operation confirmed Accessories: manual, power cable, screws, seals Main specifications: rated output 9.2W+9.2W vacuum tube 300B x 2, 12AX7 x 1, 12AU7 x 2 W385 x H217 x D325 mm weight 12.8 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. Impedance switching SW/gain VOL disassembly contact refinement, oxidation and vulcanization prevention grease application, input/output waveform confirmation, load test (1 kHz sine wave, at 8 ohm load: 25W+25W, OK) Accessories: No accessories Main specifications: output 30W+30W dimensions W410 x H160 x D205 mm weight 13.8 kg
- description
- Maintenance was carried out with attention to detail, such as replacing capacitors and replacing SP terminals! 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. (Sasaki Shota) Maintenance information: 2025.2.1 Maintained (vacuum tube sockets, block capacitors, electrolytic capacitors, oil capacitors, SP and RCA terminals, semi-fixed VR, fuse holder replacement. Load tests (8Ω load 1kHz 30W+30W), input/output waveform confirmation, and sound output checks were carried out. Impedance switching SW, gain VOL complete disassembly, contact refinement, and application of grease to prevent oxidation and sulfidation. Input/output waveform confirmation, load test (1 kHz sine wave, at 8 ohm load: 30W+30W, actual measurement) Accessories: none Main specifications: 30W+30W 50CA10 push pull W410 x H160 x D205 mm 13.8 kg

- 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. Load test, input/output waveform confirmation impedance switching SW/gain VOL decomposition contact refinement, application of anti-oxidation/sulfidation grease, input/output waveform confirmation, load test (1kHz sine wave, at 8Ω load: 25W+25W), sound output test) Accessories: none Main specifications: 50CA10 push-pull output 25W+25W (4/8/16Ω) 50CA10 x 4/12BH7A x 2/6267 W410 x H160 x D205 mm weight 14 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.
