Vintage Tube Amp

LUXMAN SQ38FD Tube Integrated Amplifier Vintage Hi-Fi Tested Working Japan. Looking for Other Amplifiers. We offer a wide selection of integrated amplifiers preamps and Hi-Fi audio equipment. LUXMAN SQ38FD vacuum tube integrated amplifier. Operation has been confirmed, and the unit is functioning properly. All rotary switches, volume controls, and balance controls operate smoothly with no significant static noise or switching shock during normal use. Contact points have been cleaned and treated for improved reliability. Tone controls and filter circuits were tested, and both audible performance and measured values were confirmed to be within proper specifications. The headphone circuit is also functioning normally. All RCA terminals and speaker output terminals are present with no looseness or instability. Please note that the PHONO circuit was not fully tested with an actual turntable setup, therefore subjective S/N performance and noise levels have not been confirmed. Basic measurements including S/N ratio, frequency response, input/output characteristics, distortion level, and maximum output were carried out, and no abnormalities were found. Stable operation was confirmed even under capacitive load conditions with no oscillation issues. The PHONO input was also checked using reverse RIAA measurement, and EQ deviation was found to be within acceptable range. This amplifier operates very stably and reflects the high-quality engineering and craftsmanship that LUXMAN is known for. The vacuum tubes consist of 50CA10 ×4, 6AQ8 ×2, 6267 ×2, and 12AX7 ×4. Tubes are a mixture of Matsushita-branded and LUXMAN-branded units. All tubes are low-noise types and were checked using a TV-7 tube tester, confirming practical usability and healthy operating condition. Most coupling capacitors are film capacitors. Random inspections of several components showed some aging in capacitance, insulation characteristics, and loss values, but nothing considered problematic for practical use. Some electrolytic capacitors, especially those exposed to high voltage, may benefit from preventive replacement during future maintenance. The amplifier is offered in its current condition. Please check the photos for details. Only the item shown in the photos is included. This classic LUXMAN tube amplifier delivers the warmth and musical richness that vintage audio enthusiasts appreciate. A beautifully engineered piece that can bring an authentic analog listening experience to any collection. This is a used item and may show signs of age. Please feel free to contact me anytime.
