The price has been reduced. 2025/3/1 sales price 138,000 yen All switch contact boards have been disassembled and cleaned, and maintenance has been completed, such as converting lamps to LEDs. This is the first Lax thin tube preamp to be in stock in a long time. Although it is a CL34 kit model, it is one where you can feel the good feel unique to vacuum tubes in a relatively clean sound. You can see a feeling of use such as appearance, dullness, small scratches, etc. (Kobayashi Hitoshi)
Maintenance information: 2025.3.1 maintenance completed (all switch contact board detachment/disassembly cleaning (excluding power switches) MUT relay replacement selector lamp LED replacement DC balance adjustment, sound output, residual noise, etc. operation check)
Accessories: none
Main specifications: used vacuum tube 12AX7 × 4 12AU7 × 4 W438 × H77 × D332 mm 6.4 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
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

Maintenance information: 2024.7.11 Maintained (vacuum tube sockets, block capacitors, electrolytic capacitors, oil capacitors, SP and RCA terminals, semi-fixed VR, fuse holder replacement. Check input/output waveforms and perform sound output checks. 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: 27W+27W, actual measurement), sound output test)
