Hi,
I was paid 23rd but not get the invoice and the tracking, via Paypal not possible to send a masage to you

I didn't get shipping info per se, but the tracking app of our national mail carrier (Austrian Post) has registered a shipment that corresponds to the Stealth Caps I ordered.
All good, no need to worry.

Do these caps have a specific orientation? I noticed some of them that came have a black mark on one end. Just want to be sure before installing.
Hello, sorry I have been delayed. All caps have been shipped.hopefully everyone has got theirs by now. I do have some left.
Yes there is a way ARC had these oriented. that was long ago and I have forgotton which way is which. listen to them and see which way sounds best.
Some of them had markings and some did not. I hooked them up in different orientations without paying attention and it sounds good.
If someone determines the correct way, please let me know.
Received my caps today, looking real nice. Gonna do some measurements regarding cap orientation/outer foil. My initial impression is that it can't be reliably determined by eye alone. I'll post results shortly.
Got mine today. Looks nice. No markings on them, but LCR check confirmed the 10uf value
Zero Cool Received mine and am extremely pleased with the purchase. Thanks for super service as well 👍
Alright, time for an update.
I determined the orientation of the outer foil by hooking up a scope across each cap and observing the AC pickup from adjacent mains powered equipment. The pics below are taken with identical scope settings, they're just different in how the probe is placed across the cap.
With these caps the effect is quite small, but consistent and repeatable. With the outer foil grounded the signal stays flat, and that's how I determine the lead going to the outer foil.
In circuit, the outer foil connection should go to the point of lower impedance. Used as a coupling cap between stages, that's usually the output of the preceding stage. Used as a decoupling cap, it's usually ground.
With the caps placed like shown below, the edge of the insulating tape can be felt with a fingernail coming from above (like when trying to find the start of a tape roll), and the outer foil leads are all to the right. In other words, with these four caps, when looking at the side connecting to the outer foil, the insulating tape is wound around the cap clockwise. Small sample size, but still...
Do any of you have similar observations? Y'all think that the outer foil connection can be determined by identifying the winding direction of the insulating tape?
