Onkyo A-SV810 / A-810 (circa 1991)
This integrated amplifier shows up under two names, Onkyo A-810 and Onkyo A-SV810, and a third, A-SV810PRO, turns up in period reviews. All three refer to the same chassis: an A/V integrated amp with video switching, surround processing, and a claimed 80 watts per channel into 8 ohms. No production years or original price are documented. The only dated source is a HiFI-Stereo test report from August 1991 (p.34), which puts the model in the early 1990s.
The A-SV810PRO reviewed by HiFI-Stereo (August 1991, p.34) had connections for a videodisc player and a DBS receiver, with S-video and composite video jacks for each video circuit. Dolby surround had adjustable delay (15 to 30 ms) in its Dolby modes. The two Theater modes adjusted room size and shape instead of delay time. The phono stage measured 43,000 ohms termination with 53 pF capacitance and overloaded at 110 to 135 mV (1 kHz equivalent). An on-screen display could show most of the information that appeared on the front panel.
Build is described as substantial. A thick aluminum faceplate and wood side panels give it heft: 9.4 kg for the A-SV810 variant. The A-810 is listed at 9.9 kg with slightly different dimensions, and the discrepancy likely comes from measuring variations or a later production change. Frequency response spans 10 Hz to 40 kHz. Input sensitivity is 2.5 mV for MM phono and 150 mV for line-level sources.
Owner reports are mixed. Some find it flat and one-dimensional at low volumes, needing a fair turn of the volume knob before it wakes up. Others say it runs impressively large and pairs well with high-sensitivity speakers. A common failure point is a bad capacitor in the tone control circuit, and the volume pot often needs cleaning. One forum user called the A-805 a better amp, which suggests a family hierarchy, but official documentation does not confirm the lineup structure.
