SANSUI T-80 AM/FM Stereo Tuner Work Vintage 1979 Display Digital Not Work Good

The article works perfectly except that the digital display has some points that do not light up and that means that the complete digital numbering is not displayed, but it does not affect the Audio and Stereo part at all, which works very well.

Therefore I am SELLING it as a defective article to remove parts or to be restored (it is necessary to change an integrated circuit that generates all the points of the digital display

Sansui T-80

AM/FM Stereo Tuner (1979)

Description

The Sansui T-80 AM/FM stereo tuner cannot drift out of tune because the FM stage has our patented Digitally Quartz-Locked System.

Once you tune and lock the FM station you want on this simple to use system, nothing can cause it to drift. No changes in voltage or fluctuations in frequency of your AC power supply, no sudden changes in temperature or humidity inside the tuner or in the environment. Nothing.

The Sansui patented system in the FM tuning section uses a digital control for its quartz-lock function. A reference (time base) signal from the quartz crystal is used to count frequency from the local oscillator (the device that does the actual tuning). If there are too many or too few digital bits to the count, the difference is converted to a correctional voltage, the local oscillator is told to go back on station, and your station is locked in until you move the tuning knob. If you turn the tuner off, a Re-Lock memory makes sure the station comes back fully locked when you turn it on again - even if you use a pre-set timer clock for recording while you are away.

The big Sansui advantage is that ours is a digital system. Others use an analogue phase comparator with quartz. But it can create radio-frequency signals which leak out, mix with the broadcast frequency you want, and cause degradation in tonal quality. Our digital doesn't.
