Sharp CD-K7000
The CD-K7000W is a shelf stero system from the year 2000 I believe. It has a 3-disc changer with VCD playback. It's an unusual system because it has 10-inch (25cm) woofers. Most shelf stereos only have 4 or 6 inch woofers. The service manual says the output power is 500 watts RMS at 10% distortion, and 440 watts at 0.9% distortion. But I'm not sure what they were smoking when they wrote that, because the power consumption is only 210 watts. The amplifier chip is a Sanyo STK4115G.
