Welcome to the Phorum Lightnin. You need to check the transformer (I assume your talking about the audio output) for resistance. If good, heat shrink the wires. As for the power supply, I'm guessing a 90V and 1.5V battery. Many have made these by conventional batteries stacked together. Like 10 9V batteries and a couple 1.5V cells. I have done a couple "power supplies" for A/C built into a battery box that work well if your planning to use the radio for a lot of time. If interested I can dig up some pictures.
