i changed d9 and its fixed it,cheers everyone,its been a pain but feel ive learnt something,it was the comment about both  op amp inputs beeing equal if there in the loop led me too it,many thanks all.,also the spike hs gone in cc mode at turn off too.
m3vuv:
well maybe i spoke too soon,just noticed i cant get the output below 35mv,rv1 does nothing,earler i dis swap c3 for a 100uf from a 47uf,is that the cause?,cheers Paul m3vuv.

You do notice that there is an edit function implemented into this forum software?
m3vuv:
