Line Magnetic – LM-503PA MONOBLOCK POWER AMPLIFIER – SINGLE ENDED 845, DRIVERS 310A – 1X24W

From £9,999.00

The LM-503PA mono power amplifier has been inspired by an original design of Western Electric. It uses a single ended 845 output stage with a 300B driver and 5U3C rectifier. The pre-amplifier stage use a special Line Magnetic tube, the 310A.

The power line is filtered by two special chokes. Bias is easily adjusted for the 300B and 845 tubes with a specific vu meter located on the top plate.

Line Magnetic’s LM-503PA mono power amplifier received the German Red Dot award In March 2017. This award is informally recognised as the “Oscar for International Industrial Design” rating this amplifier among the best in the world.
