The circuit is from old documentation but can be implemented with any modern power MOSFET. The type of MOSFET depends only on the voltage and current of the controlled load.
Found in 1968 Mullard documentation, this circuit uses period components. The transistors are...
In the figure we have a modified multiplier circuit that can operate with the sextuplicator with...
