The nelson 6W miracle (?)

[syndromet]

I decided to do a little soldering again, and had a shot at this one:

I etched the pcb, wired it up, and no  sound at all. Only thing that happens is that the chip gets hot. Realy hot!! So I checked the pcb for shorts, checked the orientation of caps and chip and checked the PS. Same problem, so I checked it all again. I guess I have checked everything a thousand times now, and I still get nothing.

I was therefor wondering if anyone have built this, and if it worked. I've checked it against the datasheet, and it seems to be ok. Any idea what I can have done wrong?

It doesn't seem as if anyone, including nelson, has built this yet... or they haven't reported back with the results... hopefully someone over at the other boards will know...

Not that I could figure out what's going on if you can't, but I can't actually read the project pdf... comes out all jumbled.. I suspect it's a mac thing.

PDF loads fine for me and I'm on a mac.  OS X 10.4.7

As far as the chip getting hot, sounds like a short to me, I would double check you don't have any stray solders or anything shorting it out.

Even if it is heating up, could you just give us the PCB layout so that we can find what is wrong man...

You'll find the PCB here. It seems to be ok, but I guess I installed the chip the wrong way or something. I'll give it another try when I get the hold of a new chip.
