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.
This 200W MOSFET amplifier circuit designed for single or mono audio channel application. You should build two similar circuits for stereo audio application. Build one first for performance testing to ensure that this circuit really wongking well with great audio performance.
The power supply used for this circuit is a symmetrical / dual polarity type. You need 4 amperes minimum of transformer with +/- 45V output. For stereo application, use about 8 amperes, although the 5A transformer is good enough 😀 . You may use the power supply circuit design on this post: 200W Power Amplifier using Transistor

this is a good circuit.I substitued the irfp250n with the igbt modules and it boosted its perfomace and it produced a high punch bass
Hello friends, my name is MD shadab from India, I’m trying to make this amplifier but here some issues, i’ve face some problems very low grid And after 5 - 10 seconds positive supply is dropped, some body plz, help me.
I am sasindu from sri lanka this is Very good amplifier today i built it using this diagram it's working fine thanks for sharing â¤ï¸

Hey!
How many Watts on 4Ohms and 8 Ohms?
Going to build it in a few days for a bass amp.
Thanks
