The power circuit using the STK IC has been popular for a long time, and is known to have good quality which is widely used in audio devices with well-known brands, such as Pioneer, Sony, Polytron and others. IC STK465 is an IC specially designed for audio devices with an output power of 60 Watts Stereo (2 x 30 Watts).

IC STK465 is designed with a hybrid circuit, namely the mixing of an integrated circuit (IC) with a transistor as the main amplifier. Therefore you can see an IC with only 2 x30 Watt output power which has a large enough dimension, because if it is dismantled, you will see a PCB inside with several IC circuits and transistors.
