Hi, I just read your post regarding your problem with your pcb on glo worm 40ff. I have exactly the same thing gone wrong with mine. I have identified a dry joint and i think the resistor needs replacing. I see it is a 27k resistor according to your post. Just looked on ebay but they have x1o or x100 values, which one shall i get? also do have any tips on the soldering bit? Thanks
