hello, I test my new smps: ir2153 powered through resistance 27k 70kHz frequency that drives two IRF840 with ei33 transformer with output 2mur1560 and 2 1000uF capacitor for symmetrical voltage 57v * 2. test classed amplifier. 50w: Well, 100w: IRF840 starting to heat up. 200w: they explode! it is their maximum power or am I wrong in something
