Okay. Maybe I wasn't clear. I understand how the voltage regulator works and what is making the noise. The fact is, it's shouldn't be making that noise and if I let it go, it burns up the regulator. I do not think that switching to another style regulator will help. It will burn up too.

What I am wondering is what is causing all this to happen. Obviously something is wrong. Honestly I could live with the buzzing. But I need it to stop burning up regulators.
