We found this circuit in an old magazine. This is an assisted ignition, where the contact breaker is kept. The circuit uses transistors that are uncommon today. Equivalents can be tested.
We find this circuit in an old documentation, but it can be made using modern transistors. The circuit...
We found this circuit in a spy book from the 90s. Transistors admit equivalents and the coil can...
The circuit shown was found in an American documentation from 1964. The circuit uses transistors of...
