X & Y caps are designed to reduce the risk of shock in one case, and fire in another. Eschewing needless complexity, let them do their jobs and install a fuse - if desired - to cover then entire appliance, designed specifically for the load involved, starting surge and so forth.

Fires & shocks used to happen due to dc rated cap failure. Hence X&Y were developed.

Old radios lacking any fusing don't meet modern safety standards. The mains plug or distribution unit fuse can't be relied on to always provide satisfactory cover. You can repair them as is or can add a fuse, the latter is safer of course.
