This is a audio power amplifier Blazer circuit provides up to 1000Watt . This interesting routes many good bass and treble alive. Importantly should choose Power supply source, which has been fairly high voltage class 70Vdc GND -70V 10A is the current low level
The transistors are 2SC3858 (NPN) and 2SA1494 (PNP), and feature high bandwidth, excellent safe operating area, high linearity and high gain. Driver transistors are 2SC5200 (NPN) and 2SA1943 (PNP). All devices are rated at 230V, with the power transistors having a 150W dissipation and the drivers are 50W.
This circuit describes an amplifier, power supply and tests procedures that are all inherently dangerous. Nothing described in this article should even be considered unless you are fully experienced, know exactly what you are doing, and are willing to take full 100% responsibility for what you do. There are aspects of the design that may require analysis, fault-finding and/or modification.
