Air TIght ATM-2 Plus Stereo Power Amplifier

“Rediscovery of the legends” Air Tight released the original ATM-2 in 1988. This KT-88 based Push-Pull power amplifier received honor of many awards and has became our longest running power amplifier model for over 30 years. Today, we are renovating this celebrated model to redefine KT-88 push-pull amplifier with AirTight`s30 years of technical expertise.   The new ATM-2Plus is a completely new design while keeping the legendary AirTight style & outlooks. All circuity including 1st& 2nd amplification and internal constructions are renovated. Unlike a time when we released the original ATM-2, vintage KT-88 tubes are almost impossible to obtain, and quality of modern tubes are different. Our focus was to lower plate voltage of the tube while keeping output power for longer tube life as well as stable operation of the amplifier. For the optimum operation point of KT-88/6550 tubes, we incorporated 6CG7/6FQ7 tubes which is more powerful than the original 12AU7 for wider amplitu
