Sansui - T-80 Tuner
Vintage De Sansui T-80 AM/FM stereo tuner cannot go out of tune because the
FM traps incorporate our patented Digitally Quartz-Locked System.
Once you tune and lock onto the desired FM transmitter on this easy-to-use system, nothing can cause it to deviate. No changes in voltage or fluctuations in the frequency of your AC power supply, no sudden changes in temperature or humidity in the tuner or in the environment. Nothing.
The patented Sansui system in the FM tuning section uses digital control for the quartz lock function. A reference signal (time base) from the quartz crystal is used to count the frequency of the local oscillator (the device that performs the actual tuning). If there are too many or too few digital bits to count, the difference is converted into a correction voltage, causing the local oscillator to return to the station and locking your station until you move the tuning knob. If you turn off the tuner, a Re-Lock memory ensures that the station will come back fully locked when you turn it back on, even if you are using a preset timer clock to record while you are away.
