Ummm.... use a smaller resistor than 39 Ohms? (If you think you need 39r to the phones, use 2.5r for current-sense and 36.5r added outside the sensing.)
> doesn't have the thermal pad
Seeing as we have 0.25-0.4W max, and will normally run nearer 0.03W or less, not sure heatsinking is really needed. (That's class B. My class A headphone amps had BIG alloy extrusions yet ran uncomfortably hot.)
