Here is an example of a farm radio which uses a 90V and 1 1/2V (combined in one case) battery. People have used 10 of the standard 9V batteries and a couple "D" cell batteries and packaged them together. The "battery" in this picture contains a small a/c powersupply to provide the voltages and plugs into the wall.
A couple of choices on how to get it running. As Brenda indicated make certain the wires are hooked up properly to the voltage source. I had a lot of fun making the "battery".
