42.5 inches of foil tape make up the capacitor part. It is sepearted with brown package wrapping paper that is red on one side... Just wanted some additional seperation for the edges of the foil tape. Caps are really close, can wrap electircla tape on the outside to tighten it up... the L1 coils are really close (136uH both) the L2 coils are kind of close, but the cores are slightly different sizes so maybe it’ll balance. They’re both much less capacitance than L1.
