[sdiy] Simple newbie: reading schematics

[Christian Hofmann]

Hi Drew,

lines like that usually indicate portions of the circuit that are
physically located outside the printed circuit board, e.g. pots that are
screwed to the front panel. On the other hand, the jacks in that GIF appear
to be sitting directly on the circuit board.

So those lines are no connections, but instead separate parts of the
circuit. Usually no electrical meaning.

regards
Christian
