Default Cap voltage can I go higher

I have some Elna caps in my CDPís PSU on the tube output stage which I am looking to change. They are rated at 100uf @ 400V, could I go higher on the voltage say 500V or do I have to use the same. I already know the voltage can be higher with output caps just wondering if it the same with other caps in other applications.
Thanks

I'd say its very important to be within the capacitor's specified voltage in ANY scenario.
Otherwise, they have a habit to go BANG! Not bad for November the 5th I suppose.

You can for shure go higher on capacitor voltage, this will be just safety with no parameters degradation.
The higher voltage the costly capacitors and larger dimensions so with the mass electronics there have to be justified compromise. In DIY audio your hands are free . Always and anyway you can change the electronic details with the same tipes rated for shure the same or higher voltage.

Thanks for your help going to buy some new caps
