Arne: I measured a couple of capacitors that I have and they are a .47 uF , so the part number ncc nc-47ct-a2 150v.47m equates to a 150V dc, .47 uF capacitor. (.47M, .47 uF, .47 micro Farad are all the same thing) If you want see if it is the cause of any of your problems you can this size of capacitor at any electronics store. It would not look correct, but will work for troubleshooting. As well, I was wrong about what the cap is used for. as near as I can tell, it is there for the reason you first eluded to, noise suppression for the radio. Which does not explain why it will not run without it? I dug through my part boxes and found 6 coils and 4 have it on the + terminal and 2 have it on the - terminal. Dan
