Does anybody know what ferrite grade is used on the fet driver transformer. I have had one burn out and have rebuilt it but would like to redesign it with better isolation between windings. Have tried various cores but cannot get the same clean waveform. The original is a gapped core of unknown material ferrite. Does anybody have a scrap amp unit that I can use for testing. The finished mods have given 1 kw at 53 volts, can be driven up to 75 volts but dummy load cannot take it!!!
