Natural Sound AM/FM Stereo Tuner (1977-79)
Every crucial part of every Yamaha audio component is Yamaha-made. That's how we set our own quality standards. And that's how we can afford to innovate every step of the way: when a part or material doesn't do justice to the music we simply develop one that does.
When you have musicians and audio engineers speaking the same language the result is full natural sound fidelity, plus innovative features which translate directly into improved tonality or operating convenience. Yamaha's insistence on total music performance, not just isolated specs, is behind a revolutionary new approach to audio component design - one that gives the CT-1010 tuner music response amazingly faithful to the broadcast signal, audibly superior to others in its class and rivalling many of the world's most expensive components.
The unusual CT-1010 front-end circuitry and components pick up the most distant, low signal-strength stations with surprisingly high signal-to-noise ratio, excellent stability, and rejection of all forms of interference.
This pays off in a much wider choice of stations, and greatly increased listening enjoyment. And not even powerful local stations can seriously overload the CT-1010, so that reception is uniformly good in any area. The front end keeps the incoming signal clean and clear of external interference, and the IF stage is specially designed to prevent internally generated spurious signals from degrading quality. One secret is Yamaha's direct assessment of differential gain, and another is the use of special low loss, low spurious-content ceramic filters and six stages of current-limiter differential amplification!
This Yamaha-developed element is precision-formed with air gaps twice as wide as conventional types, for superb frequency calibration, accuracy and stability. It is complemented by dual gate MOSFETs in the front end RF and mixer stages, and a balanced type ratio detector which combines with two ICs in the IF stage. The results a an ultra-high standard of frequency calibration, complete stability, virtually complete rejection of interference waveforms and wide dynamic range.
