Thanks for that, and do I agree about the components checking ok but being faulty under load. I believe that the problem is related to the variable resistor P5, or damage caused because of it. If I replaced all the components on this board it would work and with this in mind given the little cost and effort, I've ordered a new set of resistors and see how I get on from there.
