Air Tight ATM-1 (2024 Edition): Push-Pull Stereo Power Amplifier

The ATM-1 (2024 Edition) arrives 18 years after its predecessor, serving as a modern evolution of the original 1986 model. This EL-34 based amplifier remains true to the concept of being a "tool for listening to music," utilizing the finest contemporary components to ensure stable performance. The 2024 design focuses on authenticity over novelty, emphasizing balance to bring out the legendary characteristics of the EL-34 vacuum tube.

Key Technological Features

• Circuit Configuration: A classic Leak-Mullard type circuit utilizing Ultra-Linear (UL) connection to deliver a stable 35W + 35W output. The focus is on drawing out the intrinsic musicality and sweetness of the EL-34.
• Transformers and Bias: Equipped with reliable Tamura output transformers and choke coils. The fixed bias circuit features a custom-made precision vertical edgewise meter for effortless viewing and accurate adjustment.
• Construction: All components are hand-wired on a pure copper sub-chassis by expert craftsmen. The main monocoque chassis provides mechanical strength and acoustic benefits, featuring a design with no exposed screw heads and a thick aluminum front panel. The bottom plate is constructed from bright copper-plated steel.
• Connectivity: Single RCA input system (XLR Unbalanced available upon request). Speaker terminals are set for 4Ω and 8Ω loads (16Ω optional). The compact yet heavy-set design inherits the "AirTightness" DNA established at the company's founding.
