Up to this time, the magnetic amplifier has been considered as an apparatus controlling voltages, currents or powers with d. c. or very low frequency control signals. This paper presents the magnetic amplifier, operating well for low-level high-frequency signals, which is suitable for remote control, motor speed control and output stage of the second harmonics type magnetic amplifiers. Its faculty is exercised with the peculier transistor circuit and the parallel inserted condenser, which are coupled each other before the control winding of the first stage magnetic amplifier. The principle and the optimum conditions of operation are explained and the experimental results are shown. From these results, it was found that l0^(-8) watts high frequency signal (1 KC - 5 KC) was able to control wel1 25 watts full-wave output and that the transient response was fast also.
