I've got two soldering irons and some radio shack solder. Don't know if its good or not.
You need at least a 40 Watt iron.
You don't have to use a de-soldering tool or plunger type hand held vacuum pump, but they can help.
Radio Shack, about which I don't usually say nice things, has a de-soldering tool that looks like a soldering iron with a turkey baster attached--it's a rubber squeeze bulb.
That can be used to take out the old caps and maybe even as a soldering iron to install the new ones.
Do not, repeat, do not buy desoldering braid from Radio Shack.
They used to have some stuff that wasn't as good as the name brands, but was usable in a pinch but a few years ago they changed to some truly horrible stuff.
I recently bought this stuff
and it's okay.
would probably be okay as well, I've used Chemtronics braid with good results in the past and might get some more to compare it to the MG from the first link.
And if I were buying MG again, I'd probably get the slightly narrower version of what I got last time.
If you buy your caps from Digi-Key instead of Mouser, you should be able to find the same thing there.
I see they also have Multicore brand braid/wick which I've never seen before, but that's been a good solder brand in the past, so their braid is probably good as well.
I've been using a spool of Radio Shack 64-009A solder for a few years now and it's good enough for TiVo PS caps.
But it's probably a lot more than you need, so see if they have the same thing, only fewer feet of it.
60/40 lead/tin ratio
Do not use anything lead free or the stuff that's 2% Silver for this job--takes more heat.
If you've got some 63/37 on hand, that'll probably be just as good for this.
And the diameter doesn't have to be the same.
JUST MAKE SURE YOU'RE USING ROSIN-CORE SOLDER AND NOT THE ACID-CORE STUFF PLUMBERS USE!!!
If you have the rosin core without the solder around it, that's called flux.
That's Latin for "flow" or something like that, and flux helps melted solder flow.
If you melt some new rosin-core solder into the solder you're trying to remove, it helps to melt it more than just heating it with the iron.
