Solder, then tie-wrap the 5 coax cables J2 - J6. Trim the excess tie-wrap. NOTE:
because of the way the coax is made, chances are more of the braid will go in the
hole than the inner conductor. This is normal, unlike all the other parts and
wires. The secret is to get the coax firmly soldered and tied down.
YOU ARE NOW FINISHED WITH THE PC BOARD WORK! BREAK TIME.
PART #7: FRONT PANEL PREPERATION
You will now attach components to the front panel. It is HIGHLY recommended that you
use a set of hollow shaft nut drivers, NOT PLIERS, to tighten the nuts. This prevents
scratching. NOTE: all references to part orientation is from the REAR of the panel.
Locate the 6 Switchcraft jacks. Notice that from the rear, there is a beveled corner.
This corner is ALWAYS CONNECTED TO GROUND, USUALLY WITH THE
BRAIDED CONDUCTOR. Each jack has a flat washer, a lockwasher, and a ½” hex
nut. Remove the nuts and washers from each jack. Place aside. Keep the lockwasher
on the jacks.
Insert the 6 jacks/lockwashers, with the beveled corner in the upper right corner,
into the 6 holes. Place the flat washer on the jack, then the hex nut. Hold the jack
with one hand on the backside, keeping it ‘square’. Tighten the hex nut with a nut
driver. NOTE: when tight, not much of the exposed threads of the jack are exposed.
Check to see that each jack has the bevel in the upper right corner, and all jacks are
neatly lined up.
Locate the 2 SPDT toggle switches. Remove the hex nut (keep the lockwasher on),
stick the switches in the holes labeled AC/DC .Place the hex nut on the switch and
tighten. Be sure the switch is straight up and down: it is easy to get it slightly
off-center.
Locate the 100K Bourns 91 pot. It is blue. Remove the first hex nut, keeping the
lockwasher and second hex nut on the pot. Insert the pot into the upper right hole,
with the 3 leads pointing down towards the jacks
.
CAREFULLY, tighten the hex nut, holding the pot with one hand to keep the 3
leads pointing downwards. DO NOT OVERTIGHTEN!
You are now ready to attach the pc board to the bracket, and then wire up to the panel.
