Wiring the Power Output Tube Socket
Step 1
– Trim, strip and tin the blue wire from the output
transformer. Solder this wire to pin 3 of the output tube socket
(photo 6.17a).
Step 2
– Trim, strip and tin the red wire from pad “e”. Solder this
wire to pin 4 of the output tube socket (photo 6.17a).
Step 3
- Trim, strip and tin the yellow wire from pad “f”. Solder
this wire to pin 8 of the output tube socket (photo 6.17a).
Step 4
– Trim, strip and tin the yellow wire from pad “h”. Solder
this wire to pin 5 of the output tube socket (photo 6.17a).
Step 5
– The brown wire from the output transformer will NOT be
used for this construction. Cover its end with heatshrink tubing.
Step 6
– Neatly organize all wires tightly against the chassis.

Wiring the Preamp Tube Socket
Step 1
- Trim, strip and tin the yellow wire from pad “g”. Solder
this wire to pin 8 of the preamp tube socket (photo 6.18a).
Step 2
– Verify that the red wire that runs from the center (wiper)
contact of the volume control is soldered to pin 7 of the preamp
tube socket (photo 6.18a).
Step 3
– Trim, strip and tin the yellow wire from pad “j”. Solder
this wire to pin 6 of the preamp tube socket (photo 6.18a).
Step 4
– Trim, strip and tin the yellow wire from pad “k”. Solder
this wire to pin 1 of the preamp tube socket (photo 6.18a).
Step 5
– Trim, strip and tin the red wire from pad “m”. Solder this
wire to pin 2 of the preamp tube socket.
Step 6
– Trim, strip and tin the yellow wire from pad “n”. Solder
this wire to pin 3 of the preamp tube socket (photo 6.18a).
Step 7
– Neatly organize all wires tightly against
the chassis.
Proceed to 6.19
Installing and Wiring the Filaments
Step 1
– Trim, strip and tin the two green wires
from the power transformer. Solder these wires on
the two terminals of the installed indicator lamp.
Use the inside mounting holes of the terminals
(photo 6.19a). These terminals must not touch
each other.
Step 2
– Take the green 18awg stranded wire and
fold it in half. Tightly twist together the two cut
ends and chuck this into an electric drill (photo 6.19b).
6.17
The new upgraded output transformer has an additional brown primary wire which is not
seen in the video or photos in this manual. This brown wire is NOT used in this build. We
recommend running this wire into the chassis and sealing its end with insulation tape or
heatshrink. It will NOT be connected to anything.
