There's nothing definitive there to say whether it's defective or not.

Can you post a photo of the inside of the amp?

I try not to suggest replacing parts without a good reason but without a schematic diagram or more information about the circuit, I think replacing that op-amp may be the easiest thing to do.

It's not normal to have more than 1.5v of DC across the speaker terminals of any amp. That's the way you should measure for offset.
