Step 13
– Cut a 7” length of the black wire salvaged earlier from the power transformer.
Step 14
– Strip and tin both ends of this wire.
Step 15
– Solder one end of this 7” salvaged black wire to the opposite terminal of the AC
receptacle and neatly run the wire along the back edge of the chassis over to the fuse holder.
Step 16
– Solder the opposite end of this black wire to the end terminal of the fuse holder.
Step 17
– Cut a 4” length of recycled wire and solder one end to the middle AC receptacle
solder terminal. Solder the opposite end of this wire to the #8 solder terminal under the
mounting nut of the transformer nearest the rectifier tube socket (photo 5.20a).
Capping and Bundling the Unused Power Transformer Taps
Step 1
– Cut two 1” lengths of 1/8” heat shrink.
Step 2
– Install one 1” length per unused yellow
filament and AC input wire of the power transformer
(the green and red with yellow wires are not
capped), just covering the cut end of the wire.
Step 3
– Apply heat with a heat gun to the
heatshrink on the wire. The heat shrink should
shrink to cover the end (photo 5.21a).
Step 4
– With the heatshrink still hot, squeeze the
ends closed with fingers (photo 5.21a).
Step 5
– Tightly bunch the capped wires together
and secure with tape or zip ties (photo 5.21b).
Wiring the Standby Switch
Step 1
– Cut a 30” length of 18AWG red wire.
Step 2
– Fold this wire in half and twist these two ends together forming a
single twisted pair.
Step 3
– Strip and tin the cut ends and solder these ends to the standby
switch (photo 5.22a).
Step 4
– Neatly run the remaining length of twisted wire along the chassis
edges to V6 rectifier tube socket pin 3.
Step 5
– Cut one of the red wires at
this length and strip and tin this end.
Step 6
– Solder this end to pin 3 of the
V6 rectifier tube socket.
Step 7
– Untwist the remaining wire
and run it neatly along the chassis
edge and over to the nearest can
capacitor terminal. Cut to length and
strip and tin this end.
Step 8
–Tack solder this wire in place to the can capacitor terminal nearest the AC receptacle.

Cap and bundle only those wires that will not be used. This includes the unused filament
and the unused AC inputs leads. Do not bundle the remaining wires.
