If they have been stored at a cool temperature and are not too old then they may be OK.

It doesn't say how old they are. Do you know?

The electrolyte tends to dry up with age and heat, reducing the capacitance and increasing ESR. This makes the cap less effective.

$25 is quite expensive for a 48mF cap - I think you can do better.

One alternative could be to parallel up 2x24mF, or better 4x12mF, or reaally good 8x6mF. But this can also get expensive. And it spoils the visual effect too.

Take a look at Rifa PEH-200. That should sort you out for pretty much the rest of your life.

They'll be drier than a **** ****!

Personally, I'd go with something from this millenium like what Magura suggested.
