    Some sources suggest that these PSU caps "2x 1500uf 25v - c8/c9" should be replaced by 2200 uF capacitors. Do you see any reason to do so?
    Another thing that puzzles me is that I haven't seen any list of good quality capacitor (Rubycon, Nichicon, Panasonic...) part numbers.

    The reason I haven't done it by myself is that there are some parameters that should be checked in addition to capacitance, voltage, temperature and MTBF - like ESR. Which of these can or should be low ESR caps and which not? Is for example this Nichicon UPW or Rubycon ZLH series good for all PSU caps?

    Yes you can replace a cap for a higher uf value, and in some cases it may improve.
    But, in most cases its better to use the same value as advised by the designer of the pcb.

    P.s. the link is to a site which explane more about your question.
