Line Magnetic LM-845 Premium

The LM-845 Premium is the result of many years of research on the 845 triode Single Ended design. Thanks to its exceptional design and manufacturing quality, it is fast becoming the absolute reference in the high end amplifiers world. With a power output of 2x30W, it can be use with most of the existing reference speakers.
The LM-845 Premium is a combination of two units: One is the amplifier unit and the other is Outputs unit. In the amplifier unit the main amplifier and power supply parts are included while in the outputs unit output transformer and speaker outputs parts are included.

Amplifier unit and outputs unit are connected with two separate well-built connectors and cables for which you can put up and down or left and right.
All tube Integrated with 12AX7 input tubes, 310A signal amplification stage, 300B driver tubes and 845 output tubes. Well selected and matched tubes. Tubes we chose are Shuguang 12AX7, Line Magnetic 310A, Shuguang 300B and Shuguang 845.

Two user bias controls for 300B and 845 have been used for bias adjustment and two meters has been added to the front plate to allow you to monitor bias with ease.
Negative Feedback switch is on the front plate that you can choose between two levels of NFB to enjoy the different sound outputs.

In LM-845 Premium it includes eight transformers. Two pieces of power transformers, two output transformers, two coupling driver transformers, two chokes. In order to have a stable and better power supply we have designed two pieces of specially designed Toroid power transformers in Balance. EI type of output transformers are installed in the outputs unit separately to lower interfere from the external radio frequency.
