Being new to rebuilding valve radios, I'm looking for a little advice about replacement caps'. I'm wondering where a direct value replacement isn't available, more often the case these days, is it better to go up or down to the next nearest value.

I'm currently rebuilding a Murphy TA160 and have found replacements for some of the cap's, but just as an example I'm wondering about C56 a 4uf electrolytic, do I go down to 3.3uf or up to 4.7uf ? Being that the paper caps are, Im guessing nearly 70 years old, I'm replacing them too, but again have the same issues with nearest values, up or down ?

Cheers.
