edge behind the remaining tube sockets.
Step 40
– Run the red wire up to terminal 9 of the V3 tube socket and make a sharp 90
degree bend in the red wire so that the red wire points directly to terminal 9 of V3.
Step 41
– Make another 90 degree bend in this red wire so that the red wire points directly
into terminal 9.
Step 42
– Cut the red wire approximately 1/4” to 3/8” from this second bend.
Step 43
– Strip and tin this end and twist this red wire around the previous red wire (if
possible) to maintain uniform look.
Step 44
– Insert the tinned end of this red wire into pin 9 of V3 and solder along with the
previously installed red wire (photo 5.10b). Try to apply as little heat as possible (solder
quickly) so that the insulation doesn't contract / melt too much.
Step 45
– Trace the
twisted pair over to the
center line of the V4
tube socket and put a
90 degree bend in the
twisted pair from the
chassis edge in line
with pin 5 of the V4
socket.
Step 46
– Cut the wire
pair approximately 1
1/2” inch from the
chassis edge where
the 90 degree bends are and lay the remaining wire pair to the side.
V4 wiring
Step 47
– Untwist the wires approximately 2” from the cut end and run the red wire tightly
along the chassis edge and up to terminal 5 of V4. Reform the 90 degree bend as necessary
to maintain uniformity.
Step 48
– Cut the red wire to length and strip and tin the end. Install into terminal 5 but do not
solder just yet.
Step 49
– Run the black wire tightly along the chassis edge and up to terminal 4 of V4.
Reform the 90 degree bend as necessary to maintain uniformity.
Step 50
– Cut the black wire to length and strip and tin the end. Install into terminal 4 but do
not solder just yet.
Step 51
– Collect the wire pair previously laid to the side and untwist the two wires back
approximately 1”.
Step 52
– Strip and tin both the black and red wires of this pair.
Step 53
– Insert the tinned end of the red wire into pin 5 of V4 and solder along with the
previously installed red wire. Try to apply as little heat as possible (solder quickly) so that the
insulation doesn't contract / melt too much.
Step 54
– Insert the tinned end of the black wire into pin 4 of V4 and solder along with the
previously installed black wire. Try to apply as little heat as possible (solder quickly) so that
the insulation doesn't contract / melt too much.
Step 55
– Make two sharp 90 degree bends in these two wires at the chassis edge and lay
the remaining red and the black wire pair along the chassis edge over to the V5 tube socket.
Step 56
– Run the twisted pair over to the center line of the V5 tube socket and put a 90
