After listening to this discussion, one thing has crossed my mind.
Has everyone that has blown these caps used a vacuum pump to remove
ALL air from between the plates and in the oil? Also, is everyone
using transformer oil? I have heard talk of cleanliness, which is
indeed important. But the two point I bring up are also critical.
For those that have blown the rolled "Hull" capacitors recently, I
would like to take a survey to see if the above 2 details were
followed.
I have not built a rolled capacitor, only vertical stacked plate.
I also had problems until I used tranformer oil and used a vacuum
pump to remove all air.
