Thermal Paste

I'm using this 25W power amp:

And I'm wondering if I can use a generic thermal pad which I have laying around or if I need to use some other product.

I have built many amplifiers in my time (audio being among them). I don't believe you would have a problem.
Good luck.

Any thermal pad or paste will be OK, but depending on your design you might need electrical isolation between the IC's metal casing and the heatsink
