Default Aleph 3 input fets - How hot?

Hi All,

Just a few more quick questions before I make this PCB (layout attached).

Do the input fets require heat sinking or at least a fair bit of clearance around them?

How much clearance should I leave around the 5W 0.47 ohm power resistors?

I have come up with a fairly compact PCB design (below) and am wondering if I have left enough space around everything.

Your advice is appreciated,

Greg.

There is enough dissipation margin in the parts
that it's not critical.

Your layout looks fine.
