The resistor for oscillation in irs900 is the one 1k between the two 1nf near the amps input.the gate resistors has to be 100ohms if you are using irfp250n . The inductor try 80uh .the irs900 is not friendly to high voltage . Have fun.

By the way hadi , what voltage did you use with your aud600, and how was the sound quality?
