It is a two-channel preamp made in Japan and its model number is Beta 30. This preamp is a great addition to any hobby audio system and is sure to impress.

Nikko Beta II Stereo Pre-Amplifier in Original Box PLEASE READ Unit powers on but the Left channel is buzzy and weak. Swapping Left and Right into a power amplifier switches the speaker buzz so I am led to believe there is a problem with the Left output on this unit. Inputs and knobs all function correctly, just that issue with the Left output. Selling this unit AS-IS. Package weighs approximately 16lbs and cost of shipping varies by buyer location. Free local pickup is also available. I also currently have a Nikko Alpha II in original box up for auction if you are interested in viewing that.
