LM-170IA Vacuum Tube Integrated Amplifier
LM-170IA is a high-performance Class AB ultra-linear push-pull tube Vacuum Tube Integrated Amplifier, handcrafted with precision point-to-point wiring to preserve signal purity and ensure long-term reliability. Its power stage features four Russian KT170 vacuum tubes in ultra-linear push-pull configuration, driven via 6SN7 cathode-coupled circuitry, with 6922 and ECC82 tubes delivering accurate, nuanced voltage amplification.
the amplifier employs an EI 133*80 iron-core power transformer for abundant, stable power even under high-dynamic conditions, paired with an 114*55 iron-core output transformer that boosts signal conversion efficiency and extends frequency response. It offers comprehensive connectivity: three RCA inputs, balanced input, pure power-stage input, and a dedicated auxiliary subwoofer output.
