25W MOSFET Power Amplifier
25W MOSFET power amplifier is quite simple and uses 2 MOSFET transistor power. Power output 25 watts of output power amplifier circuit of the MOSFET obtained in loud speaker 8 Ohm load. The circuit of 25W MOSFET power amplifier can be operated using a DC voltage source symmetrical ± 33 volts with a current consumption of 2 amperes. To make the circuit 25W MOSFET power amplifier can be seen schematics and lists the following components.

Potentiometer R11 serves to set the output voltage so that 0 volts when the circuit 25W MOSFET power amplifier above is not given input signal. Transistors Q8 and Q9 must be mounted on the cooler (heat sink) to get rid of the heat generated transistor.
The circuit of 25W MOSFET power amplifier in the image above can be given input signals 200 mV of the equalizer or tone control. Output power amplifier circuit is preferably mounted speaker protectors to connect the power amplifier with a loud speaker, because the output 25W MOSFET power amplifier will generate a voltage surge when first turned on.
