The primary is left floating. There are 2 1000uf 20\% 25V electrolytics after the inductor. Eliminates all alternator hum. Remember that as men, we are in the business of making tools. I have made it a goal to create perf board prototypes, and usable electronic devices, such as this LC filter. This is modular (via barrel plugs) and sturdy enough that I can use it to filter any power supply.\relax }}{9}} \bibcite{Scherz}{1} \bibcite{eevblog}{2} \bibcite{partofthe}{3} \@writefile{toc}{\contentsline {subsection}{\numberline {1.9}The story so far}{10}} \@writefile{toc}{\contentsline {subsection}{\numberline {1.10}Potential DC DC isolated Bricks}{10}} \@writefile{toc}{\contentsline {subsection}{\numberline {1.11}References}{10}}
