Step 23 – Cut the shield wire flush with outside insulation.
Step 24 – Install 1/2” of heat shrink to the cable, covering the point where the shield exited
the outside insulation. This will insulate the ends of the shield where trimmed at the jacket.
Step 25 – Strip 1/8” of insulation from both center conductors and tin these ends.
Step 26 – Solder these ends to their appropriate terminals on tube socket, V1.
Wiring Volume, and Tone Controls
Step 1 – Lightly scrape a clean area on the back of each pot with a hobby knife. Apply a
small dab of solder to this clean spot.
Step 2 – Cut an 8-1/2” length of 16 AWG buss wire and solder this wire to each of the solder
spots on the back of the pots (photo 5.15a). It is easiest to attach the wire first to one of the
end pots and work toward the opposite direction.
Step 3 – Twist 14” of red and blue 20 AWG
wires together.
Step 4 – Solder one end of these wires to the
master volume (drawing 5.15a).
Step 5 – Measure the blue wire to the middle
terminal of the treble control, untwist and
solder in place (drawing 5.15b).
Step 6 – Direct the remaining red wire behind
the buss wire and to the bottom of the chassis.
Step 7 – Solder the 0.1 uF capacitor on the
presence control between the center and
outside terminals. Solder the cap lead to the
back of the pot (drawing 5.15b).
Step 8 – Solder the 100pF capacitor on the bright volume control (drawing 5.15b).
Step 9 – Wire the remaining controls as shown (drawing 5.15b).

The buss wire along the back of the pots is to insure that if the pots come
loose, they will not spin and break their connecting wires.
