    hi all i have settled on discreet mosfet driver using mmbt 3904&4403 as gdt, and three pairs output bjt.
    on the two tier version. the three tier one i will use lm 311 . my choices are based on availabillity of materials.

    it shall be a two tier class h, the voltage maxx shall be +/-45 , 90 vlt dc
    the fets i will use either irf ,z44,z46,z48, 1010, 1407 e.t.c

    please all check if there is any errors on schematic or what can be improved to the schematic. thanking you all in advance diy stewin
