(Knurled ridges are not quite parallel, but they're close. ## Assembly order I suggest the following procedure for assembly. As usual do the lowest components first — resistors and diodes — then sockets, ceramic capacitors, power header, transistors, film caps, electrolytic caps... Something like that.
