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

Electronic Circuit is a good site for hobbyist also who would like to try DIY because it shared good circuits. If you have a personalized circuit requirement you may feel free to request it through the comment box or contact me.


this circuit is different from the picture of the pcb and ive made this it does'nt work also the tip 42 transistor get very hot and the output resistors burn

helloo venu.. please check your buffer circuit , if there any errors?

hello admin ... is it needing filter for this pcb ....for low frequency bass ... or No needed ... ?reply please
THanks /...

Hello junatonics,

If you want the filter subwoofer, you can search here by using subwoofer filter keywords.

Hope you enjoy in my site.

hi sir, it is possible works this project if i use +/-38 volts supply? plz reply my

is it ok if i use mj15003/15004 output transistor? instead mj2995/2n3005?

is it ok if i use mj15003/15004 output transistor? instead mj2995/2n3005?

yes its possible if you use up to 45vcc .and you can use mj15003/15004 as a final transistor

hi the circuit using trnsistor bd139 bd140 transistor place ic changed
i muser the speaker volt is come 24 volt

sir some dout the circuit reial or pcb digram is original pls replay me sir
