Ah, nice, neat modification.
I assume that new caps had to be connected together to duplicate the values of what might also be described as being the size of 10-gauge shotgun shells. Those are the biggest I'm aware of. I would be learning this stuff easily enough myself, but I still need diagnostic tools. To paraphrase the old Queen Elizabeth High School motto, I (originally "We") learn to do by doing. Anyway, I once read about an old computer once that had capacitors described as being the size of Australian beer cans.
The solder you use, would that be leaded? I read here recently that the lead-free stuff isn't very good.
