75 Watt Power Amplifier Circuit
Our power amplifier only uses a handful of widely available and inexpensive components. Despite this, it can deliver an effective power output of 50 W into an 8 ohm load or 75 W into a 4 ohm load. If distortion is below 0.3% at these maximum power levels, it drops to less than 0.01% from […]
High Power 250 Watt MOSFET DJ Amplifier Circuit
The powerful DJ MOSFET amplifier circuit design provided in this article is reasonably easy to build and will produce a thumping 250 watts of music into a 4 ohm loudspeaker. Use of HEXFETs at the output ensures monstrous current and voltage amplification. The involvement of MOSFETs or rather HEXFETs at the output stage of this […]
