Wiring the Vibrato Channel Controls
Step 1
– Salvage two 3/4” lengths of insulation (white is shown above).
Step 2
– Install the first piece of insulation on the lead of the 500 pf cap (photo 5.31a).
Step 3
– Bend the leads of the 500 pF cap away from the body in opposite directions.
Step 4
– Center the 500pfd component body between the volume and tone controls and bend
the end of the insulated lead into terminal 3 of the volume control and tack solder in place.
Step 5
– Bend the end of the opposite lead of this 500pfd cap into terminal 3 of the tone
control and solder in place.
Step 6
– Install the second piece of insulation length on one lead of the .0047ufd cap.
Step 7
– Center the .0047ufd component body between the volume and tone controls and
bend the end of the insulated lead into terminal 1 of the tone control and solder in place.
Step 8
– Bend the opposite lead of this .0047ufd cap into terminal 1 of the volume control and
tack solder in place.
Step 9
– Cut a length of 20AWG violet wire 2 1/2” long. Strip and tin both ends.
Step 10
– Solder one end of this wire to terminal 2 of the tone control.
Step 11
– Tack solder the opposite end of this wire to terminal 2 of the volume control.
Step 12
– Cut a length of 20AWG black wire 4 1/2” long. Strip and tin one end.
Step 13
– Solder the tinned end of the above wire to terminal 1 of the volume control (along
with the lead of the .0047ufd cap). The opposite end of this wire will be soldered to the signal
buss ground when the board has been installed.
Step 14
– Cut a length of 20AWG blue wire 12” long and strip and tin one end.
Step 15
– Solder the end of this blue wire to terminal B on the rear of the intensity control.
Step 16
– Run this blue wire neatly over to the rear mounted footswich jack and cut to length.
Step 17
– Strip and tin this cut end and solder to the “tip” of the footswitch jack where the
other blue wire is connected. Solder all terminals of this jack.
Step 18
– Cut a length of 20AWG black wire 4 1/2” long and strip and tin one end.
Step 19
– Solder the tinned end of this black wire to terminal 3 of the speed control. The

NOTE
The wiring diagram for the 18W shows this blue wire going to the tube instead of the
footswitch. Both methods of wiring are correct. Choose the method that is easiest for you.
