Hello and thanks for looking! Here I have for sale a still in great shape Olson tubed integrated amp. It definitely works great and passes audio… A pro tech went through it last year. These vintage tube units are known for delivering rich, warm tube goodness to frankly just about anything… Especially many cold sterile digital platforms we use today! Have become pretty difficult to find in great working order. THE PICTURE IS AS IMPORTANT AS THE DESCRIPTION! Thanks for your patronage!

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. Thank you for visiting my listing!

EICO HF-81 Integrated Tube Amplifier – Restoration Candidate – Working Iron. Some units are plug-and-play. This is not one of them. This EICO HF-81 is a largely original example and should be viewed as a restoration project. The transformers appear healthy, but the amplifier will require electronic servicing for stable, long-term operation. This is for someone who will selectively change parts for stability but retain the sonic character the HF-81 is famous for. Operational Status (Please Read Carefully). Powered up slowly on a Variac. Output transformers pass signal. Video included demonstrating that both channels produce output. One channel is weaker and exhibits distortion. The stronger channel distorts at high volume. Power switch (integrated into treble knob) does not function properly. Unit is likely running on original capacitors. Given its age, full recap and restoration is recommended before regular use. Tube Complement (Installed & Working). The original Eico factory installed tubes tested weak or shorted and were replaced with. Quad Sylvania EL84 / 6BQ5 – New old stock (NOS) and new in box (NIB). Tubes are functional, but the distortion issue suggests underlying circuit components (likely caps or resistors) require attention. Classic gold faceplate with vintage wear. Appears largely unmodified internally (based on current inspection). Why This Is Worth Restoring. The HF-81 is widely regarded as one of the most musical EL84 integrated amplifiers ever made. Properly restored examples command strong market value and are known for. Balanced push-pull EL84 output. Highly respected transformer set. The transformers are the heart of these units – and this one passes signal. Collector seeking original platform for rebuild. If you’re looking for a fully restored, daily-use amp, this is not that listing. If you want a strong foundation with working iron and upside potential, this is an excellent candidate. Will require recap and service. Distortion present in one channel. Power switch requires repair. See video for operational demonstration.

Evidence suggests some of the capacitors were replaced in the past by the prior owner. Exact timing and scope of this work are unknown, but several current capacitors do not look like original factory capacitors. A full recap is recommended for long term reliability. Three 12AX7 tubes (installed and included). Brand may vary but all tested strong, no shorts and gas detected. Old tubes were all replaced for reliable performance. Classic EICO iron and EL84 sound signature. Strong, engaging mono presentation-excellent for vintage speakers. Clean cosmetics consistent with age. Some corrosion typical of age.
