Well then the PCB of this other part is that if you do not mind. that looks great (DETEX), if it were in sprint layout, or other software would be great, thank you very much in advance to all



Also if they could climb the source information and the delay speakers(off delay)

Hi irvinejay,

Why is 1n4148 not suitable? It has a trr of 4ns.
Should the gate diode be a schottky type?

Thanks

Trr 4ns but at 400mA current will heat. 1N5817/5819 has 1A will do just fine or MUR120 the best, low Trr and 1A (this is what i use in my comercial amps)

Thanks ionutzxpo,

But I think not all 1A is flowing into it because of the parallel resistor.
