Yes, it's the value 220uf, maximum voltage 16V and maximum temperature 85C that matter. If you can't find an exact match (it is a common part so you should find one easily) you can use one with a higher voltage rating or a higher temperature rating or both but stick to the same value or your amplifier may malfunction.
Note that a capacitor like that will be polarized, make sure you fit the replacement the same way around as the original. They are normally marked with a stripe on the plastic wrap to show the negative side.
