B) Twist and connect two 20AWG green wires from the top lamp holder solder lugs to V4
pins 2 & 7 (do not solder the V4 ends, yet).
(It does not matter which wire goes to which lug, but
make sure not to connect the wires to the same lug).
D) Twist and connect two 20AWG green wires to the power switch “Throw A On” and “Pole
A” lugs and give them enough length to reach the rear panel of the chassis (about 10").
E) Connect the “Pole A” wire to T9 terminal 1 (do not solder this connection, yet).
C) Twist and connect TR1 brown & white wires to T9 terminal 3
(do not solder this connection, yet).
Note: Terminals are numbered from
left to right with mounting bracket
directed towards the viewer.

Step 5 – Connect the Fuse Holder
Drawing 16 shows these connections.
A) Connect the “Throw A On” wire to the center lug of the Fuse Holder.
B) Twist and connect TR1 black & blue wires to the outer lug of the Fuse Holder

Take your time and be careful not to break any pins on the
switch or unintentionally short neighboring connections
that should not be connected.
