Recomended capacitors for GAS Thaedra regulator board 321B

Hi everyone!
This is my first post here on the forum.
I have a GAS Thaedra that needs new capacitors on the regulator board 321B.
What´s the best capacitor to replace the old ones with?
The ones sitting there is 4 1000 µF 35 V and 4 1000 µF 50 V.
