TUNER DENON TU 701 À NICE

Tuner Denon TU 701 in very good condition. This unit was sold about 64000 yens in 1977 (600 dollars). It is an exceptional tuner, one of the best ever produced. FM stereo tuner in which the drum type long scale dial plate was carried. In addition to a frequency linear 5-unit variable condenser and one step of RF, MOS FET which was excellent in the noise characteristic is adopted as a front end part. An eight linear phase ceramics filter and LC circuit are adopted as an intermediate frequency amplifier, and the degree of selection is improved to it. Moreover, the improvement of a stereo distortion is also aimed at by adoption of a broadband ratio detection circuit or a phase compensation circuit. Furthermore, sound quality degradation by interference is prevented with the high gain magnification and the seven-step limiter using high accumulation IC. An intermediate frequency magnification circuit for exclusive use is prepared for sub functions, such as a perpendicular multipass terminal, muting, signal meter, and the influence by these circuits is avoided. A large-sized level meter is formed in right and left of the front panel, and the right meter is made signal meter for the left meter with the level meter of multipass meter combination. In the right meter, not only a tuner Output voltage but measurement of external audio voltage, such as a power amplifier output, is possible.
