Hello all. I have built this circuit
http://diyfan.blogspot.co.uk/2013/03/adjustable-lab-power-supply-take-two.html (version three)
and have tested it on an 15v transformer. I have used only 6800uf cap but will add another parallel to make up the difference. I hooked this up to a scope and at 13v I am seeing a 10v 50hz saw tooth. any help to reduce this please?
