This is a vintage NAD 2200 Power Envelope Stereo power Amplifier. It has had all electrolytic capacitors except the four power supply ones replaced with high quality replacements. Several other components were replaced as well, including the output relays, that often go bad with age. The binding posts have been replaced with new nicer ones. This amplifier sounds much louder than its rated power, probably due to its dynamic power capabilities. There is a great review of this amp on Audio Science Review. (https://www.audiosciencereview.com/forum/index.php?threads/nad-2200-vintage-amplifier-review.13960/) Despite its conventional appearance, the NAD 2200 is radically different from other stereo power amplifiers in its design and performance, some aspects of which border on the spectacular. It carries a relatively moderate power rating of 100 watts per channel into 8-ohm loads from 20 to 20,000 Hz with no more than 0.03 percent distortion. In size, weight, and price, it is similar to a number of other good 100-watt amplifiers. Not surprisingly, it follows the NAD tradition of giving its amplifiers conservative power ratings and the ability to drive low-impedance speaker loads without difficulty (the clipping power output is specified as 140 watts into 8 ohms or 200 watts into 4 ohms).However, the NAD 2200—which the manufacturer calls the “Power Tracker”—has some remarkable dynamic power capabilities. Its dynamic headroom is rated at 6 dB, which means that it can deliver—in 20-millisecond bursts, twice per second—400 watts per channel to 8 ohms, 600 watts to 4 ohms, and 800 watts to 2-ohm loads. If that is not enough, the amplifier can also be operated in a bridged (mono) mode, in which it is rated to deliver up to 400 watts of continuous output into 8 ohms—or, in terms of dynamic power, 1,200 watts into 8 ohms and 1,600 watts into 4 ohms! It is also said to have a wide “dynamic power envelope,” which means that it can maintain these high levels for longer than the standard 20-ms bursts.The importance of high dynamic power output for realistic music reproduction has been widely recognized for some years. One way to achieve it is by using a signal-controlled, or “smart,” power supply, in which the output voltage is controlled by the instantaneous signal level and automatically adjusts itself to accommodate the brief high peak levels found in most musical and vocal waveforms. Since the average power requirement is usually one-tenth or less of the peak power demand, the switched-voltage design approach offers the attractive possibility of doing without a large, expensive, heavy-duty power supply whose full output will be needed for only a small fraction of the time. Instead, the amplifier can use a relatively compact, inexpensive, low-voltage power supply almost 100 percent of the time, augmented by a second, higher-voltage supply that comes into action only as needed.

I purchased this on eBay roughly a year ago with full intentions of getting it inspected and fixed. That time never came... I am now downsizing and selling my working NAD 3150 that I planned to pair this power amp with. (See my other listings for the 3150 Integrated Amp) This Power Envelope 2200 is in good physical condition, but is not working. It will power on, then go into protection mode. From what Ive researched before initially purchasing it, it tends to be a reasonable fix. Note that case is missing screws and also missing one foot. The auction is for Only the Power Envelope 2200 Amp in non-working condition ti be delivered as seen in photos.
