The LM-512CA is Line Magnetic’s flagship preamplifier.

This preamplifier uses two 6KZ8 tubes for voltage amplification, two 6922 tubes for the driver stage and American RCA 22DE4 tubes for high voltage rectification.

A selector on the rear of the preamplifier allows the user to select the phase of the XLR input, allowing connection of almost any source.

Nothing but top-grade components are used in the LM-512CA preamplifier including:

American RTX Multicap capacitors
Danish Jensen capacitors
German Mundorf MCap capacitors
NCC capacitors
Nichicon capacitors
Kiwame capacitors
Motorola high current rectifier bridge 
Panasonic relays

Line Magnetic’s LM-512CA preamplifier received the German Red Dot award In March 2017. This award is informally recognised as the “Oscar for International Industrial Design” rating this preamplifier among the best in the world.
