McIntosh MA2275 Integrated Tube Amplifier

 
The MA2275 Integrated Tube Amplifier relies exclusively on vacuum tubes in all audio circuits. This design combines classic vacuum tube audio performance with state of the art control technology.

An ultra-low-noise preamp has been engineered for the MA2275. Old-fashioned point-to-point wiring, common in vacuum tube designs, has been replaced with glass epoxy printed circuit boards developed through modern computer-aided design techniques. Input switching is accomplished inside glass cylinders filled with an inert gas to prevent signal degradation.

The circuit design of the classic MC275 power amplifier, which incorporates McIntosh’s exclusive Unity-Coupled output circuitry to provide clean, low-distortion power over the entire frequency range, serves as the power amplifier section in the MA2275.
