For an 8 ohm load, this Motorola circuit was found in a 1968 documentation. The transistors are of the time and the power supply must be symmetrical.
In the figure we have a circuit suggested by National Semiconductor, using an operational...
For experiments with ionization chambers and Geiger valves this circuit generates high voltage from...
We found this circuit in a 1979 documentation, but it can be changed to use more modern...
