Step 4 – Remove the masking tape and finish tightening the
nuts down to the board.
Step 5 – Locate the 3” wire attached to the V1 tube socket
solder tab. Solder the opposite end of this wire to the PC
board mounted solder tab from step 1 above. This
grounds the frame of V1 tube socket (drawing 6.13c).

Mounting and Wiring the Input Jacks
Step 1 – With the 1M resistor (brown, black, green, gold),
bend both leads and insert this resistor between the “tip”
and the shorting contact terminals of jack 1. Situate
resistor on the inside of the jack (photo 6.14a).
Step 2 – Run the component lead coming from the
shorting contact terminal over to the “sleeve” or ground terminal
(photo 6.14b).
Step 3 – Thread the remaining component lead coming from the
“tip” terminal over to the second jack's “shorting switch” terminal
(drawing 6.14b).
Step 4 – Tack solder the two terminals of these two jack together.
Leave room for attaching another wire later on (drawing 6.14b).
Step 5 – Repeat the above for the other two input jacks. Creating two assemblies.
Step 6 – From inside the chassis, install the first of this
dual jack assembly into the normal channel chassis
holes. The jack with the 1M resistor goes into input 1.
The lock washers go on the inside of the chassis. Tighten
down the assembly (drawing 6.14c).
Step 7 – Install the second jack assembly into the bright
channel chassis holes. The jack with the 1M resistor
goes into input 1. Tighten down the assembly.
Step 8 – Strip and tin the end of the black wire coming
from pad “G1” and connect it to the sleeve / gnd terminal
of the normal input 1 jack.
Step 9 – Strip and tin the end of the red wire coming
from pad “b” and connect this wire to the “tip” terminal of
the normal input 2 jack (drawing 6.14c ).
Step 10 – Strip and tin the end of the red wire coming
from pad “a” and connect this wire to the point where the
two normal jacks are soldered together.
Step 11 – Strip and tin the end of the black wire coming from pad “G2” and connect this wire
to the sleeve / gnd terminal of the bright input 1 jack (drawing 6.14dc).
Step 12 - Strip and tin the end of the red wire coming from pad “e” and connect this wire to
the “tip” terminal of the bright input 2 jack (drawing 6.14c)
Step 13 - Strip and tin the end of the red wire coming from pad “d” and connect this wire to
the point where the two bright jacks are soldered together (drawing 6.14c).

NOTE
photo 6.14b
Two of the four input holes on the outside of the chassis can be used as a temporary holding
place and spacing template while working with the input jacks. In this way, the proper spacing
is guaranteed when soldering the jacks together (photo 6.14c).
