120W MOSFET power amplifier by IRF540-IRF9540

Friends many you may admire MOSFET power amplifier, because of good sound and durable. Today I begs for to advise 120W MOSFET power amplifier by IRF540 and IRF9540 the circuit are the character of main Amp, Build not difficult , because of use power Supply Voltage lowness about +35V GND -35V. but use current about 3A circuit character cheap very is OCL Amplifier Class AB then good moderately sound. And systematically protect fully both of protect through the circuit a loudspeaker is damaged and other. When see the circuit has already use moderately equipment then not convenient for a novice , but still use in rows building meditation and check to repair MOSFET power amplifier. The circuit is other , get please sir.

200 Watt power Amplifier for car by 2SC2922+2SA1216

Today we try to come to see the idea power Amplifier for Car. I sees this circuit , designed come to well. There is tall drive arrives at 200W is the character Amp OCL very be Class AB amplifier make good moderately sound. Besides still systematically protect excellent loudspeaker. But I thinks this circuit may inappropriate with a novice. Because of use many equipments, circuit absorb overlap , must fine decorate thoroughly. But friends at like sound good quality As a result be worthwhile very. See be circumspect in power Amplifier for car circuit get yes.

Easy Amplifier HiFi OCL 150W rms by Transistor

A younger brother who study electronics side tell want power amplifier hifi the size about 100W to 150W is model OCL Class AB. I then advise a younger brother try out this circuit. Because of build easy must not fine decorate anything. Add finished equipment feed power supply +50V Gnd -50V sizes also the work immediately. But the equipment that use should choose well especially Bipolar Transistor parallel connection should is same number. Of the same only kind. The detail is other should see in the circuit sir.
