The amplifier comprises a core on which the load winding 1 is wound, the control 2 is hunted with the first choke 3 connected in series, the winding 4 is displaced. with a series-connected second inductor 5 and assignment winding 6, connected via a drive 7 to a transistor switch 8, a variable resistor 9, in parallel to which is connected & The terminals of the CPU are connected to the source of the signal source, and the load winding is connected via the load 10 to the terminals for the connection of the alternating voltage source. The magnetic amplifier works as follows. The voltage on the damper coil 6 T1 is formed from the load winding

2.With closed KLUKE 8, the current in the damping circuit 6 does not flow (in the absence of a DC signal) When a U signal appears, the key 8 opens, a current flows in the ueira damping winding, which, having magnetised the core, reduces the inductive resistance of the load winding 1 and abruptly increase the load current. The magnet amplifier is switched to a relay mode using a transistor switch 8, providing a boost boost. The smooth amplification is carried out by the current in the control winding 2, to which the voltage nocTOsoffloro of the current V is applied. and alternating, T15 formed by the load winding 1.
