Please review all photos closely – they’re considered part of this listing’s description. Brand: Sherwood Electronic Laboratories, Inc. Model: S-1000 II Amplifier (mono integrated tube amp). Serial Number: 6488. Power: 110-120V, 60 Hz, rated 105W. Country of Manufacture: Made in USA. Controls: Selector (Phono A/B/C, Presence, Tape, Scratch Filter, Rumble Filter, Phono Level), Equalization (AES/RIAA/Lon/LP/Ewr/Tape/Mic), Bass, Treble, Loudness (with Loudness In/Out switch), Tape Monitor (Norm/Mon). Output taps: 4 / 8 / 16 ohm speaker terminals. Includes: Amplifier unit only. CONDITION – Untested (Not Powered), Tubes Individually Verified. Tubes were pulled and bench-tested on a Sencore TC142 tube checker: 6L6 tests at 85% emission (GOOD range); 12AX7 tests at 100% emission (GOOD range) – this confirms the tubes themselves are healthy, but does NOT confirm the amplifier circuit, transformers, or capacitors function correctly. Top panel shows significant cosmetic damage: multiple names/initials scratched into the metal finish, plus general scuffing and scratching across the top surface – see photos closely, this is more than typical surface wear. Control knobs show grime/wear consistent with age; front panel lettering and chrome trim otherwise legible and intact. Not inspected for capacitor condition, cord integrity, or continuity beyond the tube bench tests described above. This is tube-era, mains-connected equipment that has not been powered on or serviced. Internal capacitors likely need replacement before use, and high voltages are present inside the chassis once powered. Strongly recommend a full inspection, cap job, and cord check by a qualified tech before first power-up – do not simply plug this in. Model: S-1000 II. Type: Integrated Tube Amplifier (mono).

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.
