Now, depending on who is asked :/ ( ask 4 people get 4 dif views, ) it may, or may not matter which way the new style film cap is put in.
some sources say it does not matter...
this says it does, :/

mentions the o-scope test.
just wondering who to believe...  |
I've ignored outside foil in 3 RCAs of that period (and basically everything I work on) and not had any issues.
The idea of connecting the outside foil to low impedance is to shield from noise. Modern film caps are much smaller and thus have less foil and lead area (smaller caps usually get wired with more direct wiring in a restoration), and are less prone to noise pick up....there might be some special cases where it makes a noticable difference, but in most cases it is more trouble than it is worth...
