If it is making bzzzzzzzt noises you might really want to consider 
replacing the cap instead? or at least checking it with a ESR meter How 
old is the unit?

I disconnected the mains straight away. I presume I need to reform the main capacitor with a dropper resistor. Is 33k a suitable value, or should it be done at a lower current than that?
