5.4.2 Red Wires (Circuit B+ and Preamp Tube Inputs)
Step 1
- Strip back the insulation from the end of the red wire
1/8” and tin the end of the exposed strands. Insert the tinned
end of this wire into the pad labeled “a” and solder. Measure and cut this wire to a length of 3”
from pad “a”.
Step 2
– Repeat above for pads “b”, “d”, and “e”.
Step 3
– Repeat above for pads “x” and “y” except extend the wires to 3.5”.
Step 4
– Repeat above for pad “j” except extend the wire to 3.5”.

5.4.3 Yellow Wires (General Signal Routing)
Step 1
- Strip back the insulation from the end of the yellow wire 1/8” and tin the end of the
exposed strands. Insert the tinned end of this wire into the pad labeled “h” and solder.
Measure and cut this wire to a length of 3” from pad “h”.
Step 2
– Repeat above for pads “m”, “n”, “r”, “s”, “u”, “v”, “w”, and “z” except extend the wire
to 3.5” for each.
Step 3
– Repeat above for pad “c” and extend the wire to 5”.
Step 4
– Repeat above for pads “f” and “t”, except extend the wires to 6”.
Step 5
– Repeat above for pad “q” except extend the wire to 7”.
Step 6
– Repeat above for pad “p” except extend the wire to 9”.

Installing the
Anti-Vibration Bumpers
Step 1
– Remove one of the clear plastic bumpers from its backing and stick it near the
center of the PC board. Avoid attaching it to any component pads.
Step 2
– Remove the remaining bumper from its backing and stick it on top of the first bumper
already attached to the PC board (photo 5.5a).

NOTE
In order to keep mechanical vibrations to a minimum, I recommend installing the two plastic
bumpers on the underside of the PC board prior to installing in the amp.
