Depending on the Schematic, I would definitely match the values as close as possible. As mentioned before, they are part of a resonant circuit with the coils to form a filter. In this case probably lower in frequency than 120 Hz because the ripple in a 25 Cycle set is lower.

When I did my 55, I used all 630 film caps in the power supply since originals were paper. They will hold up better and last longer than electrolytics. Just a recommendation.
