Luxman R-800U Vintage Stereo Receiver - Serviced

Free Shipping on *ALL* Electronics (Excluding Speakers, Contiguous 48 US States Only)

Super cool Luxman Vintage Receiver from the mid-1970's that's fully serviced and ready to rock and roll.

We replaced a bunch of parts as some had creeped out of spec and some were likely to fail in the future.

Finished it off with a tasteful LED upgrade to get a bit of "pop" from the front display.

Loaded with features including dual phono inputs (MM, Moving-Magnet), and very capable tone controls.

Service Notes:
• All electrolytic capacitors checked for value and ESR. All out of spec caps replaced.
• Noisy small signal transistors replaced.
• All functions cleaned and tested.
• Dial lamps replaced with white LEDs.

Cosmetic Notes:
• Some left / right lettering fading on the front faceplate.
• Rear speaker jacks have some damage as shown in our photos but still function correctly. 
• Originally configured for 220V operation. Now set for USA 120V operation with an adapter plug included.

The SkyFi Testing Process for Receivers:
We start with a visual inspection of all internal components to make sure there are no signs of stress or aging. Capacitors are checked for telltale sings of bulging or leaking, resistors are checked for signs of overheating or cracking, and transistors are checked for signs of stress or damage.

We then power up the unit carefully and run a simple 1k sine wave while monitoring the output on an oscilloscope for signs of distortion or noise. Finally, we run the receiver to its full rated power into the appropriate resistive load provided by our Sencore amplifier tester. If there is an issue, it will usually be noticeable at this point. If everything reads clean, we will often test for THD (Total Harmonic Distortion) measured by our Keithley distortion meter, and compare it against the original manufacturers specifications. The receiver then remains powered on to "burn in" on our test bench for a few hours to make sure there are no heat related issues. If there are balanced inputs available they will be also be tested.

Then the tuner is thoroughly tested in our lab utilizing our professional Sencore SG80 FM Generator, which allows us to generate a reference FM signal of any frequency and amplitude, and then measure the resulting tuner output on our Sencore PR81 or oscilloscope.

Final testing involves pushing actual music thorough the receiver. We've learned over time that some issues are only noticeable to a trained ear while listening to familiar source material. Our test bench has reference vintage KEF speakers that we're very familiar with which quickly reveal any discrepancies. Some receivers will then move into our listening room where they are tested with our in-house reference speakers of choice.
