The good capacitor is not labeled like a normal cap, so I dont know what
value it is. It says K 505J 250. (I am guessing its 250 volt, but I am
clueless about the uf value).
I did figure out one thing on my own (using Google).
505J is a Japanese way of marking a cap. In this case, it's 5uf.
So it's a 5uf at 250V cap. I can only guess the "J" means Japan.
J is quite likely to be the tolerance code.
Electronic starters can improve a flaky fitting - but I'd just rip it out
and fit electronic ballasts, you get more light and/or less electricity
bill. The tubes also last a lot longer.
LED "tubes" are starting to appear on the market - you can probably expect
better than half the electricity usage.
Leaving the PFC capacitor in can take the edge off mains spikes, but to
protect an electronic ballast, a MOV is worth the effort.
