[sdiy] PCB op-amp layout - 2x2 or 1x4

[Ove Ridé]

What I've seen on some boards is having all/most ICs lined up in the
middle of the board and the power traces going between them. Then you
have separate (sub)circuits on the left and right side. This technique
is of course especially useful if you have two copies of the same
circuit on one board, so you can essentially mirror the circuit on
either side.
