I have had two issues on the Superadio I and II. By far the most common is that the AM RF amp transistor will fail. Easy to check for this... If you look at your tuner, you'll see that one lead from the antenna goes straight to one tuner section. Locate the larger of the other two sections and touch a screwdriver to that connection. If the radio gets louder, than the RF amp is your problem.
