Finally, let's make the chassis Ground connections.
Retrieve the Green ground wire from the Mains transformer and the Green IEC ground
wire, using a nut, tightly secure the two grounds: the Green Mains Primary wire and the
Green wire from the bottom lug of the IEC socket to the chassis ground lug, as shown below.
Next, let's test these important connections. Using your multimeter's Continuity setting, verify
the following:
IEC socket ground to Chassis Ground
IEC socket Neutral to IEC PCB White solder tab
IEC Line (Hot) to IEC PCB Black–Grey Solder tab
Finally, peel off the paper covering on the plastic insulating board, then, using the IEC
hardware, mount the IEC PCB to the back of the amplifier above the Mains transformer as
shown in the picture above: use a 30 mm screw, a short standoff, then the PCB, another
short standoff, and finally the plastic insulating board and a nut.
