No.
Go and search for lm1876 and also download lm1876 datasheet.

I just discovered a few of those ICs in my collection. Looks simple enough to build something but rather than reinvent the wheel I'd like to find some artwork someone has created for this. I don't find anything in the data sheet.

But 20W per channel is awesome for such a little unit. I also have a few LM4780 chips that will put out 120W; I'd like to make a project for that one also.

I think its two LM1785 in one package. Do a forum search for LM1875 in the chip amp section. Theres loads of these floating around, try Google too.

go and read again. the 4780 cannot put out 120W. It can do 60W from each of it's two channels if properly assembled.
