If you mean like the one at top LH of your first picture, next to the transformer, they will be wax dipped silver mica and are very reliable, so best left alone. As has been said, the ones which are candidates for replacement are waxed paper tubular one and brown Hunts ‘Mouldseals’. Wax paper caps often had a black ring at one end, which signifies the outer foil, but they’e Not ‘polarised’.
A popular replacement type for tubular paper caps are tubular polyester 630V capacitors which cover most eventualities. They abound on internet in a wide range of values, and from traditional component suppliers.
There’s a yellow/red Plessey electrolytic, which I’d be inclined to change.
Whatever you do, don’t change several capacitors without testing after each one, because if you do, and you’ve made an error, you’ll have quite a palaver tracing and rectifying the error.
Good luck in your endeavours.
