Line Magnetic LM-300IA – Single-Ended Integrated Tube Amplifier
02.05.2025 07:01 | ~1 minute read
Line Magnetic has introduced a new single-ended integrated tube amplifier Line Magnetic LM-300IA, based on the iconic 300B triodes. The device is handcrafted and equipped with output transformers and a bias regulator with a precise built-in current meter.
The complete tube set of Line Magnetic LM-300IA includes PSVANE 300B for the output stage, Electro Harmonix ECC81 and two Tungsol 6SL7GXT for the input stage, as well as two LINLAI 274B driver tubes. The integrated amplifier Line Magnetic LM-300IA is equipped with a specially designed high-quality toroidal power transformer and two wide-bandwidth EI output transformers. All transformers and capacitors in the amplifier are sealed. Of course, the LM-300IA amplifier works in pure class A. The volume control is implemented on a high-quality motorized ALPS potentiometer, which can also be controlled using the remote control.
Line Magnetic LM-300IA operates in the frequency range from 10 Hz to 50 kHz and offers a power of 2 x 10 W. The retail price of the amplifier in Europe is 3,990 euros.
