Sony ST-S707ES Vintage ES Series AM/FM Tuner


Featured in our latest Sony Killer System video, this S707ES is one of the best from that golden Sony era.

This example is in great condition but the wood panels do show some aging. Please be sure to review all of our listing photos. Both panels can be easily removed if you want a perfect unit, and replacement original panels can be found online for sale from time to time (Audiogon, eBay, etc.).

Tested in our shop and listening room and working properly throughout.

The SkyFi Testing Process for Tuners:
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.

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 tuner into our test system. 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 tuners will then move into our listening room where they are tested with our in-house reference speakers of choice.
