The LM-845IA is a quality upgrade of the old LM-518 amplifier. It delivers twenty-two watts per channel. Single ended design, Pure Class A, Integrated Stereo Amplifier with 845 output power tubes. The rear-illuminated front panel meter is used to adjust the polarization of the tubes.

The use of high quality components (Realcap capacitors, ALPS potentiometer) wired in the air for the most part is the guarantee of exemplary reliability. Its transformers output are of EI type, specially disigned for power supply.

Its power and current capacity allows it to manage a very wide range of speakers. The use of the legendary triode 845 offers a listening to an unusual musicality.
