Hello All! My friend has an Emperor TS5010 that he accidently hooked up backwards to his home power supply. He says that when he trys to plug it in now it shuts down his power supply. I've been doing some looking around but not coming up with much. :headbang Needing to know if there is a protection diode inside that would've taken the punishment and is now in need of replacing. I'm now wondering if this is the reason that some of the power cords come with dual fuses.<?> Anyway, hopefully this is not the end of the road for the Emperor. Thanks guys!
