Step 1
– Locate the 20AWG red wire attached to
terminal T20. Strip and tin the end and solder it
to the bottom terminal of the input jack nearest
the chassis surface (terminal B - photo 7.7a).
Step 2
– Locate the 20AWG red wire attached to
terminal T22. Strip and tin the end and solder it
to the top terminal of the input jack nearest the
chassis surface (terminal A – photo 7.7a).
Wiring Filter Cap & Cathode
Resistor to Chassis Ground
Step 1
– Locate the 18AWG black wire attached
to terminal T50. Strip and tin the wire end and
solder it to the chassis power ground.
Step 2
– Locate the 18AWG black wire attached to terminal T56.
Strip and tin the wire end and solder it to the chassis power
ground.
Wiring Voltage Divider Resistor to B+
Step 1
– Locate the 18AWG red wire attached to terminal T52.
Step 2
- Strip and tin the wire end and solder it to the “A” terminal
on the 50x50 can capacitor (photo 7.9a).
Wiring the Indicator Lamp and Filaments
Step 1
– With the turret board mounted in the chassis, locate the red
and black twisted 20AWG filament wires.
Step 2
– Neatly run these wire to terminals T59 and T60 on the turret
board.
Step 3
– Cut to length and strip and tin these two wires.
Step 4
– Bend a small hook in each wire and tack solder the red wire
to T59 and the black wire to T60 (photo 7.10a).
Step 5
– Neatly run the two wires from the indicator lamp to T59 and
T60 on the turret board.
Step 6
– Cut these two wires to length and strip and tin both ends.
Step 7
– Bend a small hook in each wire end and tack solder these
two wires in place, one wire on turret T59, the other wire on the turret T60.
Step 8
– Locate the two twisted green filament wires from the power transformer.
Step 9
– Neatly run these two wires from the power transformer to T59 and T60 on the turret
board.

Soldering these two wires is quite a challenge if you are using a large soldering iron. You
may want to remove the board to wire these and then install both together into the
chassis.
