Input Jack Construction
This jack is isolated from the chassis. Make sure it is not grounded by checking continuity of the inside (sleeve) of the jack to ground.
The center (shunt) lug was drilled a touch oversize to handle all of the wires going into it. This jack can be wired in different ways depending on
Your preference so this is only a guide. Top lug soldered in. Hold off on soldering the rest until you have everything positioned.
Another bit to make for the coaxial cable ground.
Loop and Ground Wire installed and soldered
