Leaking brass joint

[pikaluk]

I have a bought and plumbed in an old (antique) brass towel rail/radiator. One of the brass joints (that is soldered) is leaking - it's a tiny leak but enough to be a problem.

I've tried plugging it with putty which doesn't work - how do I repair it? The radiator cost a lot - I must save it!

Thanks.
