What caps to use in my Cd player?


I have a Xindak SCD2 that I would like to upgrade to parts.
Currently, I would like to replace the smaller caps in the power supply w/ black gates. However, I have established that they are 25V/47UF, but, I am not shure what type of cap to use i.e. -N, NX, NX-HiQ, FK,Standard, PK ect.

Any help would be greatly appreciated.

To answer your question requires measuring the actual working voltage across the 47uf/25v caps. Also is the power supply a linear or SMPS?
