Hi
see picture with suggested caps. thanks both for the advice. Now working fine. I did see the spikes on ground and moved my vss connection point to the ov pin on the 7805 before my post and had a small improvement. My scope showed this point to be clean.(it is a PC based scope. keep my good scope at work. May not be quick enough to trigger on the spike). But probably not clean enough. You can only find out what you don't know by doing something first and apparently circuit design isn't my strong point.
