Query: Been through 2, don't last long

I have purchased two of these now. The first one starting shorting out after 6 months. I have to adjust the volume slowly to get it to almost "tune in." I chalked it up to a bad model, so I bought another. The second started doing the exact same thing after a month. It is a pain. I am going to find a better model this time.
