D4K5 DIY Class D Amplifier 2000W ( Gerber Files) - working PCB or fake ?

[makus ele]

Working amazingly well, great low freq response, ideal for subs. Thanks Sunil.

WHICH COIL DID YOU USED ?

irfp260N should not hot, btw need to see switching freq, if more than 250khz ofc irfp250 and 260N will be heat slow rds on, change gate resistor 33 ohm, but the power output will be less. if you want full power for 250/260 change freq to 250khz then it will be ok. yes inductor is very important no 1 in class D amp, wrong inductor will cause lack power at output, i have build pair version this amp with irfp260N, very stable at +88 -88 vdc

WHICH CORE DID YOU USED?

i guess it is a good amp because wakhu post video on you tube of all his amps while they are working and also testing them with a huge load. e.g full bridge at 2ohms

my design , based on etjale 1200 watts .
the amp is clear but the hf noise at low volume is the issue
