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.
Mosfet audio amp circuit diagram.
Many people also use it.
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.
Capacitors c3 c4 c5 must be rated 50v and c2 can be 10v.
Hi fi 100w mosfet power amplifier circuit.
Do not expect much performance from this amplifier.
Different types of mosfet amplifier circuits with diagram and schematicsa list of various audio amplifiers of output 10 watts18 watts50 watts using mosfet.
Use a 8 ohm 15w speaker as the load.
These are npn and pnp power transistors.

This filter section is created using the r3 r4 and c1 c2.
The first objective is to attain a considerable power gain that is sufficient to give a noise free audio signal at the output through speakers.
The circuit can be assembled on a vero board.
2sc 5200 and 2sa 1943 is complementary transistors which are mostly using for power audio amplifier building.
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.
The gain stage uses a potential divider biased mosfet amplifier circuit.
