Capacitor outside foil
#1

I get the idea that installing caps with the foil to ground reduces the noise floor. New caps don’t come marked so you have to do this yourself.

I’ve not been doing this - and haven’t really noticed any issues on any of the radios I have repaired. 

I’m redoing this Heathkit O-12 oscilloscope right now. Would this matter more in test equipment?  I’ve got a Kenwood SM-220 station monitor with an oscilloscope function so it’s not an issue to take an afternoon and mark the foil ends.

My apologies if this is a dumb question. Perhaps everyone does this and I’m slow on the uptake.
