I need to build a dual volt PSU and I am struggling to find a schematic that works.
I need +6DC & -6DC 200ma each from a single AC supply. (I realise a transformer with dual secondary's would solve the problem but I need to run this from a single wall mounted plug-in PSU - 12 to 15 VAC)
One schematic I found that almost got there is shown below. This does work until you try to get 200ma from the +6 rail, then the 7806 complains.
(test circuit did use capacitors but not shown in picture)
All suggestions welcome.
