Here is simple LED-power audio amplifier ambit with MOSFET amplifier TL071C and 2 may be up to 45 W into 8 ohms. For MOSFET IRFP240 and IRFP9240 are acclimated assurance with accessory can now be these modification.
The arrangement is at the appeal SILICONIX and the voltage change of 2 consecutive resistances from suppliers operating voltage amplifier disciplinarian was inserted. MOSFET charge be army on at atomic one condenser 1K / W.
Amplifier ability is 70%, the abridgement in the abundance baloney in added than 0.2% at 20 Hz at 8 ohms and 10W. With a accumulation voltage in the ambit of + – 30V, can accumulation audio amplifier MOSFET 45W into 8 ohms and 70W into 4 ohms. Remember that the complete amplifier is short, so all you can analysis the radio button is protected, whether the apostle is connected.
