The amplifier section of the NAD model 120 has directly coupled output stages, with a linear frequency curve of 20 to 20,000Hz at a nominal output, ensuring excellent bass reproduction and dynamic range. The tuner unit is of the most up to date design. The superb results are made possible by the 3-gang variable capacitor with low noise FET and 2 FETs in the RF and mixing stage as well as IC and phase linear ceramic filters in the IF amplifier. Most important is the MPX circuit with phase lock loop which increases stereo separation to more than 40dB at 1kHz. The tuner has separate AM and FM IF amplifiers. For accurate tuning a field strength meter is used. The unit has been revised and has been serviced. I have put too much love of this unit to revive it and make look shining again. The wood case cover has been repainted, knobs and potentiometers have been cleaned and deoxitized so expect a crack free sound. All pictures are original of this lot and part of description so what you see is what you get !
