This is a web page http://muamp.com/uAmp-energiser.html that I wrote a while back. The info' has has been published on Head-Fi by me in the past. At the bottom of the web page, it shows two different ccts for bias from the mains, I prefer the second one as it has fewer components, although the first one allows you to adjust the bias voltage to what ever you want by changing the potential divider resistors to different values . Both have mains isolation transformers but still need you to be electrically competent.
about the last one,
What the size of the elements that requires?
- What diodes (IN4007 1A 1000V) and capacitors (uF and Voltage) to use?
- How much Watt acceptance use for the Resistors ?
