8. Jacks (J1,J2,J3): The 1/4” jacks can only be installed in one orientation on the PCB (74). They
can be soldered in much the same way as the headers: hold them in with one finger while you
tack a pin down with solder on the other side of the board (75). It is very important for the jacks
to be perfectly perpendicular to the board, so make sure they are sitting flush against the board
before you solder the rest of the pins; otherwise, the assembly may not fit into the chassis properly.
Solder in J1, J2, and J3 (76). Because of the tight spacing, when soldering J2 keep your soldering
iron on the outside of the pins so as to stay away from the pins of U4 (the charge pump IC). It’s
also helpful to not use lots of solder on the pins of J2 that are close to the pins of U4 to ensure none
of the pins get shorted.
