Moth Phono Stage

I have a Moth 30 series Phono Stage that I think is an earlier one(12v edition) from the 90's.Anyway would switching out the electrolytic capacitors 2-35V 2200uf and 2-40v 470uf for more recent(i.e 50v 2200uf and 63v 470uf respectively) ones be a worthwhile upgrade? Please excuse my ignorance.
