Use a 8 ohm 15w speaker as the load.
Mosfet audio amp circuit diagram.
Many people also use it.
The circuit can be assembled on a vero board.
Use 30v dc for powering the circuit.
The gain stage uses a potential divider biased mosfet amplifier circuit.
Do not expect much performance from this amplifier.
Circuit topology is about the same of the above mentioned amplifier but the extremely rugged irfp240 and irfp9240 mosfet devices are used as the output.
Different types of mosfet amplifier circuits with diagram and schematicsa list of various audio amplifiers of output 10 watts18 watts50 watts using mosfet.
To celebrate the hundredth design posted to this website and to fulfil the requests of many correspondents wanting an amplifier more powerful than the 25w mosfet a 60 90w high quality power amplifier design is presented here.
2sc 5200 transistor amplifier.
Using 3 ics in a bridge model.
The power transistors of the 400w amplifier circuit are bjt 2sc5200 2sa1943 or mosfet irfp240 irfp9240 can be used for this and will change materials for use.

How to make an audio amplifier using just one mosfet transistor an audio power amplifier or power amp is an electronic amplifier that strengthens low power inaudible electronic audio signals such as the signal from radio receiver or electric guit.
Capacitors c3 c4 c5 must be rated 50v and c2 can be 10v.
2sc 5200 and 2sa 1943 is complementary transistors which are mostly using for power audio amplifier building.
So the transistors are using in power audio amplifier circuits.
To achieve this the following stages were employed in the amplifier.
