Beautiful looking Marlux with green scale light. Amplifier works perfect, but FM tuner is mono only.. Good for phono amplifier. Picture are part of the description 2x 15 watt RMS stereo with built-in phase shift system The MR-215 from Marlux is the AM/FM receiver par excellence for the novice hi-fi enthusiast who opts for audio lessons at an affordable price. A continuous power of 15 Watts RMS per channel, both output into 8 ohms, means mature 2-channel stereo and rich reproduction with a harmonic distortion of less than 0.8%. The KR-215 has a built-in phase shift system, allowing a quadraphonic effect to be achieved by connecting a second set of speaker boxes, without the use of intermediate equipment. Naturally, the KR215 has connection options for a record player, cassette deck, etc. Progressive technology and sophisticated construction ensure that your KR-215 is easy to use and can be repaired if this ever becomes necessary.
