Hi, I picked up a dead 7075 recently, I found that the fuseholder was not making contact with the fuse, fixed that fault and now the PSU area was making a fizzing noise. 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? Regards, M K

MK 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?
