Front panel controls I
We now get to the most 'busy' part of the wiring layout - the control panel, with its input, pots and
switches. There are dozens of wires and it would look chaotic if all were done at once, so I've broken it
down into several steps to make it easy to follow. Take your time and, once again, double check each
connection. Start by wiring up the input socket.
TIP: Many experienced amp builders find it easier to do the initial wires for the input socket and
some other individual components outside of the chassis. You can temporarily mount the socket to the
front side of the front panel. This gives you full access to the lugs and keeps it stable while you solder.
You need R1, some shielded wire and some black wire. First, trim and bend
the leads of R1 so that it connects lugs 1, 2 and 4 of the input socket (the lug
numbering is shown in red here). Note: one of the resistor's leads passes
through lug 4 and passes back diagonally to attach to lug 2. The other end is
connected only to lug 1. Don't solder any of the lugs yet.
Now take about 12cm of the shielded wire and strip one end of it, so that you
have a short length of shield (twisted together to make a single wire) and the
separate centre conductor. Solder the centre conductor to lug 1 of the socket
and the shield to lug 4.
We'll ground the input socket, but it's easier if we add the necessary wire
to the chassis first (it's a very crowded space if we leave it until later). Take
about 8cm of black wire and solder one end to the ground lug on the
bottom of the chassis, shown here. Bend the other end of the wire out of
the way for a moment.
Now install the input socket inside the chassis. Take that black wire you
added to the ground lug and connect the end of it to lug 2 of the input
socket. Solder this lug. Note: there is nothing to solder on lug 3 of the
socket.
At the other end of the shielded
wire, strip back the outer insulation
and the shield. Discard both and
then use some heatshrink to cover
the exposed end of the shield (this
ensures that it cannot short against
any other part of the circuit). Connect and solder the inner
conductor to the turret that's connected to R2.
