i could get round to finishing the page on the 20W amp i built. the chip (LM1876) is electrically compatible (i.e pinouts EXACTLY the same) as the 40W stereo model so without ANY modification you can build either the 20W or 40W stereo amp with ease

here's the simple layout for building it on stripboard:

here's a pic of the power amp module once built:

and the underside:

just say the words and i'll put up a complete page on how to do it

(here's the finished amp)
