Hello,
Do you have another radio to test with? That will tell you if it's the radio or something else.

Don't know how electrically handy you are. But try taking the radio out, take the shell/cover off of it. Look for bad capacitors/condensers. Usually they are the main culprit to power fluxutations. If so, replace the those bad caps.
