Line Magnetic LM-170IA Integrated Amplifier

from $10,800.00

LM-170IA is a high-performance Class AB ultra-linear push-pull integrated vacuum tube amplifier, meticulously handcrafted using precision point-to-point wiring to preserve signal integrity and ensure exceptional long-term reliability. Its output stage is built around four Russian KT170 power tubes operating in an ultra-linear push-pull configuration, driven by a 6SN7 cathode-coupled circuit, while 6922 and ECC82 tubes provide highly accurate and refined voltage amplification.

The LM-170IA features a substantial EI 133 × 80 mm iron-core power transformer, delivering abundant and stable power reserves even during demanding dynamic passages. Complementing this is a 114 × 55 mm iron-core output transformer, engineered to maximise signal transfer efficiency while extending frequency response and preserving tonal accuracy across the entire audio spectrum.

Designed for system flexibility, the LM-170IA offers a comprehensive range of connectivity options, including three RCA line inputs, one balanced XLR input, a pre-amp input, and a dedicated subwoofer output for seamless integration into high-performance audio systems.

Made to Australian standard of 240V~. Australian local warranty.
