Installing the Rubber Grommets

Installing the Output Transformer
Step 1
– Twist the red, blue and brown primary wires together.
Step 2
– Twist the yellow, green, and black secondary wires together.
Step 3
– Feed the two wire sets into the grommets (photo 6.4a). The
red, blue, and brown wires go into the grommet nearest the power
transformer.
Step 4
– Pull the two wire bundles tightly through the grommets
leaving the transformer flush on the chassis.
Step 5
– Secure the output transformer to the chassis with two #8
KEPS nuts and the two #8 x 1/4” screws. The two KEPS nuts should
be mounted on the inside of the chassis.

Installing the Octal Tube Sockets
Step 1
– Prior to mounting, slightly bend the solder terminals on the back of the socket
outward (photo 6.5A).
Installing the 9 pin Tube Socket
Step 1
– Prior to mounting, slightly bend the solder terminals 1 - 3 and 6 –
9 on the back of the socket outward, leaving pins 4 and 5 alone for now.
Step 2
– Using a pair of needle nose pliers, carefully bend terminals 4 and
5 together. The holes of each of these terminals should meet flush
against each other (photo 6.6a).

The new upgraded output transformer has an additional brown primary wire which is not
seen in the video or photos in this manual. This brown wire is NOT used in this build. We
recommend running this wire into the chassis and sealing its end with insulation tape or
heatshrink. It will NOT be connected to anything.
NOTE

This photo does not show the
brown wire (see above note)
The terminals of these sockets will break if bent too far. It is recommended to use needle
nose pliers for better control when bending these terminals.
