the fact that the majority of fuses are on the incoming AC line, not on the rectified and filtered DC. Your lack of understanding makes you a perfect candidate for the pseudo-scientific claims foisted by Ted Denney and his Synergistic Research con men.
He has no idea, for any fuse to be detectable the "right way around" it would have to be acting like a diode, which it’s not!
It’s a 10c glass fuse within it is a piece of resistance wire, designed to burn up at a certain amperage, then it’s wrapped in fancy Orange suit and sold to the gullible idiots for $160!!!!!!!!!!
