power supply cap question

[PurpleTheory]

Hey guys,

I'm planning on building a PS like this:

Here is the transformer that I have:

I have a bunch of 10,000uF caps that i got a while back that I was hoping to use, but I noticed that they are 25v. I was wondering if these will work, being a +-PS.

Thanks,
Matt

I don't think it'd work.

(heres a very nice article on power supply stuff
http://www.geofex.com/Article_Folders/Power-supplies/powersup.htm )

and If I understand things correctly, the 22V your transformer is putting out, becomes something around 30 after rectification, which would be bad for those caps.
and still with the +- stuff, you're looking at each side of the powersupply seperately, so from 30 to 0 and from 0 to -30, too much


You could wire the pairs of caps in series to got 5000uF to 50V though.

What is the output current range?  10,000uF capacitance is a hell of a lot unless you are constantly pulling an amp or so.  Otherwise I would go for a regulated supply with a lot less front end capacitance.
