What works for me as a hobbyist who is never in a hurry. Your tastes may vary: Visually go through each board. Write down what is installed, uf, voltage, diameter, height for big caps, pin spacing, low leakage or not, non-polar or not. Then spend some time on Mouser or Digikey looking for suitable replacements.
Takes longer, but you get to bond with your new toy, and to find board marking / manual errors, signs of damage and failure, previous repairs, undocumented factory changes, and so forth.
Kinda like having a few dates before . . .
