Hi,just got my Crack and about to start. Want to install Mundorf MCap's from beginning as I don't want to then desolder standard caps to install the Mundorf MCap.
Question I have is in the Crack manual the 100uf 160V cap has a striped side that is attached to 6U  and the other caps striped side to 10U.
I have check other posts that people did with Mundorf MCap's,but can't really make out which lead goes where. The MCaps's themselves don't have anything on them as to which is the end with the shield on the outside. So can anyone that has installed them let me know which side of the MCaps is the striped side?
Thanks

Film caps have no polarity so you can install them either way around.  There is no way to know which end is the outer foil on the MCaps without testing them on an oscilloscope, but it really doesn't matter so don't worry about it.

Found out that the shorter lead on Mcap is the outer foil,do I hook it up then as being the striped lead then?  If it doesn't matter,Ill just make sure I use the same  side of of the caps when connecting to 6U and 10U.

No - the stripe on electrolytics is the negative so it goes to the load (headphones), but in the case of films it's good practice to put the outer foil to the lowest impedance, normally that's the 6080 cathode, with the inner foil to the headphones.

But, as robertone1 said, it is not important, partly because this is the highest signal voltage so there is almost no chance of picking up hum from electric fields that is actually audible, no matter which way the orientation goes.
