15K. Plug in the "AC Input" Molex plug onto the Molex strip labeled J2.
The locking header holds it snugly in place.
16K. Take the other end of the coax that you soldered to the board in step
14K and connect the BNC connector to the BNC barrel you placed on the
rear panel in step 13K.
That takes care of that! We're almost ready to plug it in the wall and give her a
run. But first we want to check everything we have done up to this point very
closely. Especially the circuitry involved with the line voltage connections.
Check and double check your wiring against that shown in the diagram and
pictures. Also make sure that the two high voltage connections are to either
side of the Molex plug and not in the center. The green wire of the line cord is
Earth ground, not a high voltage connector. It can be connected to either of
the center pins of J2.
Be very careful around these connections. When we plug it in they will
always be live! Especially be careful of the power switch S1. The top
pins on the switch are connected directly to the ones mounted in the PC
board so line voltage (117 VAC) will be present on those as well!
When you have completely finished the unit and it's up and running, you may
want to coat these connections with nonconductive 100% silicone (such as tub
sealant). Be careful to not get it inside the switch movement however or you
won't have a good switch any longer!
