Here is the 200W MOSFET amplifier powered based on four piece of IRFP250N, they are very cheap and easy to find in the electronic market in your area. The circuit has been assembled and tested with very good performance.
Here is the 250W RMS power amplifier circuit called Legend-Stage Master. This is the previous version of Legend-Stage Master MK2. The circuit is based on power MOSFET and give a great output performance for indoor audio sound system.
Here the 50W AF power amplifier circuit powered with single IC STK4036II. This circuit will deliver 50W single channel output. The amplifier circuit uses symmetrical (dual polarity) power suppy. Recommended power supply voltage is +/- 35VDC. Use heatsink to prevent overheating on the IC and maximize the STK4036II performance.
This 200 Watt high quality power audio amplifier will give you top class quality for loudspeaker 4 – 8 ohm. Frequency range 20-20000Hz, Voltage 24-36V with current max 5A. You need heatsink to keep the transistor from overheating. Itu use dual polarity power supply to work, then you may use this power supply to supply… Read More »
