Mr Blue,

what's the verdict on Sparky ?
Sparky is a great little amp. Lots more authority than the regular LM3886 and runs a lot cooler than the Krell. It got a little more hummmmmmm (but its not something you can notice unless you really try) than the 3886 but that's possibly due to my sloppy wiring. I am quite happy with it.

The thread on Sparky is here.

Are you using the original IEC-320 inlet? I would reconsider this. If you are the only one who will be working with this, that is OK, but if someone else is going to touch this, then it would be a very good idea if you labelled it accordingly to avoid them inadvertantly plugging it inot 120VAC or even worse, 240VAC. Just a thought.

You are completly right.This will be only for personal use.But I did make cable for it, so I don't think some would use it in normal 230ac outlet, unless he/she would like to see sparks, heavy smoke,big bang,...

Hmmmm. I think the feedback path is far too long and the supply caps are too far from the chip.
