Sony 2010
Little is documented about the Sony 2010 as an audio component. The model number isn't in the standard Sony equipment directories or in the brand's own product indexes from the period. Its exact identity is unclear from the surviving records.
The review recorded about 100 watts per channel into an 8-ohm load. That is well above the rated 65 watts (Audio-Collection, p.117). Into 4 ohms it was weaker, dropping to just 50 watts, which the reviewer blamed on current limiting from the protection circuitry. Peak current capability measured 10 amps, though the report suggested significant nonlinearities and distortion showed up below that limit. Harmonic and intermodulation distortion were both adequately low, and bandwidth was described as fairly well restricted outside the audio band.
Period advertising from 1995 uses the "2010" suffix on entirely different Sony product lines - the SPP-2010 cordless phone and the IT-W20 accessory. Those are telecommunications devices, not audio components (HiFI-Stereo, 1995, p.31). A 1966 Audio item also references a "Videocorder TCV-2010," a video tape recorder running ¾-inch tape at 7½ ips. Whether any of these share a chassis or design lineage with the amplifier tested in Audio-Collection is not documented.
Beyond that one test report, almost nothing is recorded. No service literature, no owner's manual, no further reviews, and no collector pricing data have surfaced. The Sony 2010 remains a name with a single measurement and a question mark.
