Re: NVPD
Because all the electrolytic caps are the same value, you can probably get a price break by buying ten, but even if not, they won't cost very much. Just be sure that whoever solders them in is aware that electrolytic caps are polarised, i.e. they have a distinct 'positive' and 'negative' end and must be inserted the right way around. The pcb may be marked to illustrate the orientation, but of course the simplest way is to make a primitive drawing of the orientation of the old components before removing them, and then making sure the new ones are inserted the same way around.
If you can solder, you can do this yourself, you don't need electronics knowledge, it's simply replacing like for like (assuming you have the correct replacement caps). Just be sure to orientate the caps the right way around.
