WTB: In Line IEC Mains Filter

[Firebottle]

The bridge is limiting the voltage across the capacitors.

The best description of why and how is this http://sound.westhost.com/articles/xfmr-dc.htm

Ben says that he is stupid......join the club. I now remember building something like this many years ago, not sure if it worked or not



I assume the proprietory bridge works in the same way.

Yeah, that's the one Alan.

The bridge is designed to keep the AC voltage across the caps to about 1.4V. The caps form a non-polarised 2000uf plus single cap by connecting positives together. The AC mains passes through the caps to your gear but leaves behind the DC which is on all AC mains. The DC Duffers have a ferrite choke on the power cord mains side and an EMI\RFI filter after the DC blocker section. Also I fuse the unit to 4A. These days they are built in ABS enclosures. Any plugs or sockets can be fitted.

Most report an instantaneous improvement in sound even with other power conditioners after the blocker. Any audio gear with a toroidal transformer is badly effected by even a few milliamps of DC.
