Re: Leak 2000 Stereo AM/FM Receiver

The highest-class receiver of a leakage company.

The output stage of power amplifier is constituted from pure complimentary type OCL, and is strong to the in-use cage and the load variation about the constant current circuit in the Class-A driver stage.

To the input stage of the preamplifier, the differential amplifier is aiming at reservation of an in-use cage, high S/N, and a precise equalizer curve. Moreover, in the MPX demodulation part of FM, the PLL decoder has realized the in-use cage and the stable separation.
