.....The 4/8 on mine had been worked on previously. The cardboard was missing and new caps silicon-ed in the can. I'm doing similarly only filled in the end with cardboard and poured in some bee's wax to make it look a little better.

In hindsight I should have used beeswax on my 3 x 10 MFD, but on the 4/8 (and also the 12/20) there is a circular cardboard piece that fits on the end of the tube so you don't see what's inside anyway.... at least on an original capacitor. Maybe if I find my beeswax (lost in the move) before I put it back together I'll redo the 3 x 10...

   

I just checked all of my tubes and they all look good except for a 6A8 that was in place of a 6L7 so I replaced that one. I got brave and also pulled the 6T5 and on the tester it does light, but I'm pretty sure it will be too dim to actually use, but I'll try it just to see how bright it actually is.
