Audio Research VT-100 mk II stereo tube amp [Expired]


no longer for sale

This is an Audio Research VT-100 mk. II stereo power amplifier. The amplifier is in excellent condition. It was manufactured in March of 2000 and is rated at 100 watts per channel at 8 ohms. I purchased this for a second system about 5 years ago and just have not used it enough to justify keeping it. It has the same tubes (Svetlanas) as when I bought it, so I cannot tell you much about their age. The amp sounds just fine to my ear, so I have never been motivated to change them out. Auction includes amp, original double boxes and packing materials, power cord, jumpers for unbalanced inputs, and owner's manual. Sorry, no shipping outside the US. More details on the amp from the web: Power output 100 watts per channel continuous from 20Hz to 20kHz. Approximate actual power available at "clipping" 110 watts (1kHz) Power bandwidth (-3dB points) 15Hz to 80kHz Frequency response (-3dB points at 1 watt) 1Hz to 100 kHz Input sensitivity 1.9V RMS (Bal or SE) for rated output. (23.5 dB gain into 8 ohms.) Input impedance 200K ohms Balanced, 100K ohms Single-ended.
