I have an Acoustat TNT 200 amplifier that is not getting any use. I have owned it over 15 years, and it continues to work well, but it is wasted driving surround speakers in a media system. It is in good overall condition, although the mouting bolts that hold down the cover are mismatched--as they are not stripped, they can easily be replaced. The amp was well known in its day, and has a tube like sound. from a solid state amplifier. It is Full MOS-FET'S from inputs to outputs. Rated power per channel into 8 Ohm load, 200 Watts, 4 ohm load, 325 watts.
I have an owner's manual that I downloaded from the internet According to it, the amp has a very fast rise time, fast slew rate, and 400K Hx bandwidth. The output impedance is essentially zero,and the damping factor is over 1000:1. No current limiting fault protection, and low feedback (for a solid state amp)
I am offering at less than the Audiogon bluebook average.
As I am in the office I will be posting pictures later.
