In this paper, experiment and analysis of a new firing circuit for Silicon Controlled Rectifier (SCR) which compensates the supply voltage variation are described.　The circuit is composed of two half-wave type magnetic amplifiers (i,e.,Ramey type and self-saturation type magnetic amplifier) which are connected to cascade by a coupling resistance. The circuit is analyzed by using the equivalent circuit method, in which the characteristics of magnetic cores and of rectifiers are represented by an appropriate approximation. The relation between the gate circuit resistance of the first stage magnetic amplifier and the coupling resistance is verified by the analysis.　As a result, it can be said that the fluctuation of the load current of SCR amplifier is only 0.5% for a supply voltage variation of ± 20 % by the experiments.
