John, If you can find 2 identical Caps, why can't you find 4? From a technical document I found you don't really need protection on just 2 caps. Once you move up the # of caps above 2 zeners are recommended.

I seriously doubt they are measuring and matching caps to make the 5V version.

The are just the 2.7V one internally connected. G
