Air Tight ATM-300 , 300B Amplifier , Only 3 years old

Up for sale is the amazing ATM 300 from Air Tight. It is with deep regret that I must sell this jewel of an ampfier, I have switched to electrostats which need a lot of power. I am the second owner and bought this unit from a factory authorized Air Tight dealer in Hawaii last year. Feel free to verify , the Dealer, Drew Shane at Hifi Hawaii. At that time the unit belonged to a guy who lived in Hawaii only part time and the unit only had 50 hours on it when I bought it. Under scrutiny I find a few minor paint imperfections on the transformers. Otherwise the condition is excellent. Comes with stock tubes with approx. 100 hours on them. The 300b tubes are new Electro-Harmonix Gold Grids. I have original packing and will double box.Tubes will ship separately.

The Absolute Sound 2007 Editors' Choice Awards: "The Air Tight ATM 300 is one of the handful of 300B SET amplifiers that lays claim to magical sound extending beyond the midrange. The amp's airy highs, natural tonality, and low-bass extension defy common perceptions of 300B SETs."
