My LX200R has a right angle power tip, so I haven't had this problem. But, I'd assume that taking the adapter to Radio Shack or another electronics store would be the best thing to do. If it's not something that exists, you can always buy a right angle tip and rebuild the power cord yourself. It's pretty easy to do if you have the right tools.
Hope that helps a little bit.
