I'm restoring a vintage O-scope and its brightness isn't quite where I think it ought to be yet. I'm not a recap and ask questions later kind of restorer. (But I'll do it if I see that that it needs it.) I've only had one or two pieces of gear malfunction because of bad caps, so owing to experience, I wait until there's a problem before I go that route. There are some questions that I'd like to get advice on before I start wading into it. The first indicates THIS entry in the SM: "40 + 40MF 315V". (x2) Electrolytic What does this mean? I know that having a slightly greater voltage rating is a good thing, but I've read that you need to stay pretty close to the capacitance ratings. In the machine, I find these: (They look like electrolytics, FWIW.) One set of caps: .2uF 1kV Other cap: .2uF 2kV BUT the SM says these caps are supposed to be .1uF 1.4kV (first set) .1uF 1.5kV (the individual one) Will they sub out for each other? (I know this much, they're not easy to find.) Thanks in advance for any help. My experience with CRT's is very limited. This isn't in my traditional wheelhouse.
