1. THE METHOD OF MAKING AND BALANCING A PULSE TYPE SHOCK RESISTANT MAGNETIC AMPLIFIER WHICH COMPRISES THE STEPS OF: (A) PLACING A PREDETERMINED NUMBER OF THIN LAMINATIONS OF MAGNETIC MATERIAL OF ANNULA R CONFIGURATION INTERSPERSED WITH ANNULAR PAPER SEPARATORS OF LIKE CONFIGURATION IN A CLOSELY FITTING ANNULAR METALLIC NON-MAGNETIC CORE BOX HAVING A PLURALITY OF PERFORATIONS THEREIN, (B) PLACING A NON-METALLIC, NON-MAGNETIC PERFORATED ANNULAR COVER ON THE CORE BOX AND TIEING THE COVER THERETO AT INTERVALS WITH A LENGTH OF CORD, (C) TOROIDALLY WRAPPING THE BOX AND COVER A LAYER OF POROUS GLASS TYPE, (D) WINDING A PRIMARY TOROID WINDING AND A SECONDARY TOROID WINDING ABOUT SAID TAPE WITH A SECOND LAYER OF GLASS TAPE BETWEEN THE WINDINGS, (E) COVERING THE WINDINGS WITH A THIRD LAYER OF POROUS GLASS TAPE IN TOROID CONFIGURATION TO FORM A TOROIDAL TRANSFORMER, (F) CONNECTING THE PRIMARY WINDINGS OF A PAIR OF TOROIDAL TRANSFORMERS IN SERIES AIDING AND THE SECONDARY WINDINGS IN SERIES OF OPPOSING RELATION, (G) PLACING A MAGNETICALLY MATCHED PAIR OF TOROIDAL TRANSFORMERS IN BACK-TO-BACK MUTUALLY OPPOSING RELATION WITH A NON-MAGNETIC SPACER THEREBETWEEN AND TIEING THE UNITS TOGETHER AT INTERVALS WITH CORD, (H) AND WINDING A PREDETERMINED LARGE NUMBER OF TURNS OF A TERTIARY WINDING ABOUT SAID PAIR OF TRANSFORMERS AND COVERING SAME WITH AN ADDITIONAL LAYER OF POROUS GLASS TAPE.
