OCL Subwoofer amplifier TIP3055-TIP2955

Power amps OCL circuit for subwoofer included in the category of easily assembled because the circuit is very simple and does not require setting bias, stay to make the PCB track, install the components and can be used.


As shown in the figure above OCL amplifier circuit, there is no need in the settings, so assemble OCL power amplifier module is as easy to assemble amplifiers using IC. You can use the output transistor TIP2955-TIP3055 or MJ2955-2N3055 generate 75 watts of power which is powerful enough for a hi-fi amplifier at home as well as for power subwoofer. Below the pcb layout design for OCL power amplifier subwoofer
