The ABS plastic will be hard to hack open..
You need a hacksaw and cut around it.. put it in a good metal casing for proper grounding and 'improve' the regulating circuit.. Not that I have not done it before.. wink.gif

Exactly the same thing i did smile.gif but i didn't use hacksaw, use even crude (stupid) way to hack up.
These adaptor if can get dirt cheap at junk store, it serves good as cheap transformer, everyone know how expensive it is now sad.gif
