This pcb was heating for mewhen i made it. I had modified little bit. I had removed 1uf capacitor from output. And used 22uh coil. Ms157-2 sendust red core with 42 turn 1mm coper wire. It is not heating that much for me. All class d pcb have same combination at output. use 22uh core with 680nf to 1uf capacitor better replave 2x470nf and remove both 1uf capacitor. www.google.com/search?client=ms-android-samsung-ss&sca_esv=f61bafd3095e347f&sxsrf=ACQVn0-nYo1e015s5UAxbd0PfeVb6RxjqA:1707974256756&q=class+d+amplifier+circuit+300+watt&tbm=isch&source=lnms&prmd=isvnbmtz&sa=X&ved=2ahUKEwiy2-_2y6yEAxVazjgGHedyBhAQ0pQJegQIDBAB&biw=384&bih=728&dpr=2.81#imgrc=d0Bx27Ny079nVM&imgdii=y960VwLKqBjUWM
@@generaldiy Yes I also modify the coils. I had to increase it and it reached 79uh and it didn't heat up much but its diagram indicates 30uh and with that capacity it heats up the inductance hard.
I do not have any testing equipment and 30-0-30 10 amp transformer. As some people say, it will produce near about 250 to 300 watt on 4 ohms. It have some drawback it is heating a bit, it required little bit bigger heat sink.
What number of enameled wire do you use for the coil or how many millimeters, and what size or code is the ferrite ring to buy it, thank you

@@henryquispe1701 if we use 35uh and use 1uf capacitor it will not heat. It depends upon matching of coil and capacitor at output.
How it îs on mids and highs??
good for mid and low.
