This power source was found in a 1968 Electronics World. The transistors are from that time. The current of each output is limited by the transformer.
The signal itself captured by the (long) antenna serves to feed this simple experimental circuit....
This circuit outputs a signal modulated by a unijunction oscillator. The circuit is from a Radio...
Found in a 1965 Motorola documentation this circuit drives magnetic-type fuel pumps found in cars...
