    All those waxed caps will be bad. By teh way, if the wax is too cloudy to read the print, hit the cap with a heat gun and the wax will melt away. And the wax that sy=tays will have cleared enough to see through.
    I was hoping to use some of these old caps, but I suspect you're right that they will all have to go. Surprisingly all the resistors are really close, so I plan on leaving them alone

      The wax guys are paper dielectric, and that wax is not a perfect seal, so over time, they get contaminated. I don't think I have ever seen a wax cap that wasn't leaky. Well in recent history. Back in the 1950s we used them and they were OK then.
