My poor Plus just had its second Analog Board die, most likely C1, as I have the vertical line down the middle of the screen. As I inspect the previous Analog Board I had in it, C1 has vented its top. The one on this particular Analog Board is a 3.9 uF, 35 volt electrolytic. I've seen other revs of the motherboard with a 3.9 uF 100 volt cap in it. (Obviously using a cap with a higher voltage rating is not generally a problem.)

I'm looking to get some replacement caps to fix these boards, and I'm finding 4uF caps rated 250 volts. Has anyone fixed their Analog Board using a 4uF cap, and would it be okay? 3.9 and 4 are so close, they're within the 10% tolerance rating of the 3.9 cap, right? I should be able to use a 4 uF cap no problem right? I'm just checking to see if anyone knows if I'm about to make a giant mistake or something.
