Gary,
Just gone through a massive lightening storm here a moment ago so everything 
was off for a while, yes the caps are Ok, I have actually swapped out the 
transformer and tried it under a light load, exactly the same, I will be 
'hot dipping' this evening see how it is tomorrow, fingers crossed.... here 
goes.
