Please print the pcb on a 1:1 scale.
Objects might be closer than they appear
(I found out the hard way, for my own pcb it looked like there is plenty of space for big caps but there was just enough room for normal caps)

These things go together really easy, nothing very hard to solder.

The size is 1.5" x 1.75"

Liking it. I don't think I'll bother with my single sided board attempt now

Single sided boards are so mutch easier to design. Double sided are a pain to design.

The design isn't so bad, the board production and soldering is the pain.

Thanks to all for the support and advice!

I am tweaking some of the pads and spacing this morning just to make this thing a little more polished, and after that I will will post the eagle files for everyone to enjoy. Cheers!

My tip is to allow a bit more room around the zobel resistor, try not to bend the legs so close to the body. Doesn't need much more room though. You could also lose a bit of the ground plane around the backside of the chip which would allow you to bring the mute trace in a bit and the board smaller/chip closer to the heatsink/better clearance for the trace-heatsink. Do you have to bend the chip legs a bit as it is, to get it flat against the heatsink?
