Here's your chance to grab a great Audio Research amp with some real power for a song! Rated at 100 watts per channel into 8 ohms, this amp can easily drive most modern day speakers with ease! In superb shape, this amp has only one owner in it's lifetime and has been carefully used (almost all medium to low volumes) in a smoke free household. Stereophile magazine said this when they tested it a few years ago: "This is a truly excellent power amplifier that combines the musicality of tubes with the dynamics and bass extension that characterize the best solid-state, and enough power to drive most speakers to satisfyingly high levels." Tubes have approx. 1500-1800 or so hours on them, but are good for up to 3000 or so, so quite a bit of tube life left. Tubes used in this piece are four 6550s (output tubes) and 5 6N1Ps (input and driver tubes). These are very easy to find and compared to most other tubes very inexpensive! This amp has single ended (RCA) inputs only (is not a "balanced" design) Amp looks and works perfectly and is ready to upgrade your system! Paypal adds 3%. Ck out my feedback and buy with confidence!
