Control system for high-tension power transistors in a key circuit, containing a unit of connected transistors, preferably in a Darlington arrangement, characterized in that between the collectors of each transistor (T1) of a preamplifier and each transistor (T2) of the final step amplifier, at least one diode (D1) is connected, preferably two diodes (D1, D2), where the collector of each transistor (T1) of the preamplifier is connected to the anode of one diode (D1), and the collector of each transistor (T2) of the final step amplifier is connected to the cathode of the second diode (D2).<IMAGE>
