nx-Amplifier: 100 W CFA topology Amp
I've just posted up a write up and some pictires on my website (follow the link in my signature below) on my latest amp. This is based somewhat on the sx-Amp, which you may recall I posted up in August last year. However, that was a 15 W per channel class A amp whereas the nx-Amp is class AB 100 W. I am very pleased with the result - really great sound.

The link for the PDF does not work.

I just checked it on another computer - it works for me. Can you try again?

The link still does not work (from the page) strangely enough, if I get the url for the pdf and copy it to the address-bar then it works (windows Vista, MS-explorer 9).

Thanks Kasey - glad you enjoyed reading them! I'll post up the gerbers and BOM list for the nx and sx Amp in the next few weeks - I am just a bit busy for the next week or so.
