30w Amplifier Diagram. If you want a stereo power amplifier please check out the other schematics. For the record this is not a 30 watt amplifier it s actually 44 watts and this is because each one of the tda2040s is capable of outputting 22 watts when the voltage is 18 20 volts.

For the record this is not a 30 watt amplifier it s actually 44 watts and this is because each one of the tda2040s is capable of outputting 22 watts when the voltage is 18 20 volts. This home audio amplifiercan output 30w with a 32v symmetric power supply. Simple circuit with higher power output this amplifier circuit is very easy to build.

This is 2n3055 amplifier circuit diagram 30w output ocl and integrated on one pcb without ics so cheap and low noise.

It is small size for mini room. If you want a stereo power amplifier please check out the other schematics. 30 watts audio amplifier circuit diagram. The power amplifier section employs only three transistors and a handful of resistors and capacitors in a shunt feedback configuration but can deliver more than 18w into 8 ohm with 0 08 thd 1khz at the onset of clipping 0 04 1w 1khz and 0 02 1w 10khz and up to 30w into a 4 ohm load.
