      The B-class power amplification system widely used in the amplifying the aural signal has the properties of low wave-distortion and the good power gain at the large amplification lwvwl, but has the disavantage that the power gain is decreased with lowering the signal amplitude. The BD-class power amplification system has high power gain, independent onthe signal amplitude, but it has the short coming of large wave distrotion.
      In this paper, we reports on the development of the hybrid type BD-class power amplification system which is the combination of the above two. In this results, we developed a amplifier which has the large power gain and the low ditoration ratio.
      It's power gain was 80% at the large amplification level, 45% at the low level and the distoration ratio about 0.1%.
