Stereo integrated amplifier employing a Class B-A operation switching main amplifier.
The main amplifier section employs an all-stage direct-coupled pure complementary OCL circuit, eliminating interstage capacitors.
Furthermore, it achieves high stability through a two-stage differential amplifier and a transistor-based bias stabilization circuit. FETs are used in the bias circuit of the first-stage differential amplifier, providing ideal bias characteristics due to their constant current characteristics.
The power stage operation mode can be switched between Class B and Class A, allowing the user to freely select between the stable power of Class B and the low distortion of Class A.
The power supply section employs a large-core power transformer with excellent regulation and 18000μFx2 capacitors, as well as a high-capacity 250A surge current rectifier diode.
In addition, a separately set constant voltage power supply is used to drive all stages except the power stage, improving the overall stability of the amplifier.
