I bought this amp in a collection from an audiophile home. There was no power chord when I bought it. After reading how particular spectral equipment is I quickly plugged in a generic 3 prong chord just to see if it powered up. It did power up I quickly shut it off No further testing has been done. It’s very clean inside no funny odors. This amplifier is huge and has to weigh close to 100lbs. I’m selling for parts or repairs. When it’s sells I’m taking directly to ups store and they can be responsible for packing. If you don’t like this please don’t bid. I’m in Ohio if you’re out west I probably wouldn’t bid nothing seems to make it that far no matter how well it’s packed. Hifi vintage audio amplifier class a 2 channel monster power.

SPECTRAL DMA-200 Full Class A Megahertz Power Amplifier.RIGHT CHANNEL IS WORKING , GREAT SOUND.++ HAS ISSUE: LEFT CHANEL THE SOUND NOT CLEAR (NEED REPAIR)RCA/XLR Audiophile High Quality.BIG AND HAVEY WEIGHT : 50 POUNDS.MADE IN USA.Spectral DMA200 Megahertz Class A AmplifierYears ago, Spectral introduced the DMA-200 Class A amplifier. In front of todays technology, at high speed and power, this amplifier represents a very different, innovative, radical amplifier design, inspired by the high technology and instrumentation used by the Silicon Valley.With its Ultra Wide Band capability and high power signal response, the audio industry has redefined the worlds top segment A Class amp design and performance with its success in the audio industry. Even if only the Mega Hertz operating principle can be applied, the Spectral DMA-200 is still ahead of our time. Working at the Megahertz level; means that it can process the incoming signal more quickly (or even more quickly) than all other amplifiers; which means that it has a very positive contribution to sound qualityClass A @ 8 Ohm 200 watts WRMS / channel pressureClass A @ 4 Ohm 380 watts WRMS / channel powerVacant Power Consumption: 1200 Watt, continuous (this is due to high power consumption, working principle in full Class A of the device)
