This is the application note from IRF about using their products for linear audio amp. Never built it and never heard of someone who built it either.

But IMHO just by looking to the circuit this is a very basic circuit and could be better in some aspect so I don't recommend it.




(BTW the original is at www.irf.com in the application note section)

Good circuit.

Most of the difficult design issues addressed, well documented, simple.

Excellent start point for 'mosfet' sound.

Try it. You won't be disappointed.

Cheers,

Hugh

I think also since this amplifier has been discussed in the forum quite a few times one could probably find something useful in:
