Follow the layout provided and connect the centre of the co-ax cable to the right side
potentiometer lug and the co-ax shield to Ground, left side. Be sure to ground only at this end
of the cable.
Connect the centre of the other end of the co-ax cable to V2, pin 2.
Input Jacks
To wire up the input jacks, it is easiest to remove the jacks from the chassis, set the spacing per
channel pair correctly to match the chassis, wire them with the 1M Carbon Film resistors and
jumpers and then reinstall them. Leave enough wire flying lead for the ground wires on the
input jacks go to the pre-
amp ground and about 6” to reach the board from each jack. The
ground wire and insulated jacks are another improvement over the original design. Use wire
from the input jacks to the eyelet board
Install the Switchcraft switched input jacks. Use the supplied black shoulder washers to
insulate the jack from the chassis. This is an improvement in design for noise reduction. Refer
to the diagram and install the washers with the shoulder of the outside inserted
into
the
chassis. The rear washer has no shoulder or if it does, faces
away
from the chassis and they are
sandwiched in place by the jack and mounting nut. Tighten securely. Once installed, test to
confirm that there is no electrical connection from the jack to chassis.
Then connect and solder the leads to ground tag and input leads to the 4-68K input grid
resistors on the board.
