Hi Im interested in the idear of using the Lm3886 ic HTTP://national.com as driver insted of output amp it self.

It must be posible to let the lm3886 or maybe lm1876 stereo chip. Drive to pair of out transistors like Mj11015/11016 Or bigger output transistors

If the lm 3886 is mounted on the same heat sink the termal protection will work and protect the output stage as well

I don't know much about the designing of a circuit my self

so if somebody find the idear( got it from a guy on the net) interesting then please help.

The point is to make a very easy to build and low cost power amp of about 400W rms depending on output stage.

hope to hear from somebody

happy new year to all :-) jc.
