I recently burned up some secondary windings on an Edcor 131. The fuse didn't blow. I'm not a 100% sure, but I think it's the 6.3V taps, at least the ohm readings were off and they weren't on the other taps. I notice on the board that the high voltage center tap is grounded to the board ground and then to IEC ground. Not so with the 6.3V center tap....which might explain why the fuse didn't blow? Could somebody educate me on this? I can see that 6.3V isn't a threat.
