Smell them! Blown capacitors smell peculiar!

Bulging = bad

Those look like the 105 degree C rated, not the lower 85 C light blue ones which wont last long in that application.

I think the fancy low esr types are tan in color, but check to see if they have "low esr" written on the sides anywhere, you will need the same for replacement.

So basically same voltage, same temp or higher and same uF rating for replacement.

Yes indeed. You need to replace with capacitors of the same voltage, heat,
and capacitance rating. Also they have polarity, so install them with the
negative side facing the same position as the bad caps.
